I want a windows installer to install my application that's written in python, but I don't want the end user to have access to my source code.
Is that possible using python? I was using cx-freeze, but that has the source code available. So does pyinstaller. I think gcc does, too.
Does anyone know of a way to do this?

Fundamentally no, it's not. Python code will always be distributed as
some form of bytecode. The only way to make it available without
revealing anything is to put it on a server and let people access it
without running it themselves.
But why is that a problem? Copyright law protects you from people
stealing your code and making unauthorized changes to it, and if
you're not worried about them making changes, there's no reason to
hide the source code (whatever you distribute would be just as
copiable). Are you concerned that people will see your bugs? We all
have them.

The OP is asking for source code not to be available, not bytecode.
There are obfuscating tools like PyArmor you might want to have a look at.

It would help if you would explain what you want to accomplish and why. Do you expect to make money off your software? If not, why do want so badly to protect it?
The most basic answer is that your code is automatically protected by copyright law unless you say differently. But it is still a good idea to state outright what actions would be allowed and what would be forbidden.
If you do expect to make money, you could look at what phone apps developers include with their apps. And it would be good to consult a lawyer who practices in this field.

You have access to Gmail's front end source code. Your web browser runs
it every time you use the service (and probably while you aren't using
the service, too).
My educated guess is that Google expended some
effort to hinder you from looking at and/or analyzing (or do you say analysing?) that code, and that their lawyers will come knocking at your metaphorical door if they so much as think you are using that code in
some way other than running it inside your web browser. If only this situation were a cruel April Fool's Day joke.
You don't have access to Gmail's back end source code.
Many/Most web apps follow this pattern to varying degrees. I do not
know whether this setup meets the OP's requirements.

If your needs are basic, you shouldn't need a lawyer. Copyright law
and treaties DO protect you. But it's important to be aware that no
amount of legal protection - whether you hire a lawyer or not, and
whether you identify copyright and license or not - will stop people
from copying your code. NOTHING will stop people from copying your
code if they have access to it. All you can do is discourage them.
So that brings us back to the original question: Why protect your
*source code* specifically? There are two extremes available to
everyone:
1) Distribute the source code. Let everyone see it. Stick a license on
it that permits them to use it, modify it, distribute modified
versions. Set your code free and let it be used.
2) Don't distribute the program *at all*. Don't distribute the source
OR the binary. Instead, permit people to *access* the program - which,
in today's world, usually means a web service.
Both of these are very popular and work well. I don't have access to
the Gmail source code but I'm using the service. I don't have access
to the Twitch.tv source code but I'm using the service. Meanwhile, I
have Python programs running on a Debian system using the Linux
kernel, invoked using bash, served from an ext4 mass storage device,
etc, etc. I have the binary code for all of these, and I'm legally
guaranteed access to the source if I want it, so there's no incentive
to steal it.
The middle ground of "distribute binaries but stop people from
accessing the source" is a much narrower use-case, and I would say
that it's not actually a single use-case but a family of them, each
with different needs and requirements. So it's essential to know what
you're actually trying to protect, and why.

I am writing an app but I’m not sure I’ll sell it yet. I have it in a private GitHub location and GitHub prompts me for a license. I don’t really understand licenses so I just picked Apache 2.0. Maybe I’m going too far with my worry about whichlicense I pick. I’m not selling it now so it doesn’t matter. I have to do a lot more work before I get to that point

Cython can compile a script to C source code for a module or executable (--embed). The source can be compiled and linked normally.
For example, the following builds a "hello.exe" executable based on a "hello.py" script.
cython -3 --embed hello.pyHello, World!
set "PYI=C:\Program Files\Python311\include"
set "PYL=C:\Program Files\Python311\libs"
cl /I"%PYI%" hello.c /link /libpath:"%PYL%"
copy hello.exe embed
embed\hello.exe
I extracted the complete embeddable distribution of Python 3.11 into the "embed" directory. You can reduce the size of the installation, if needed, by minimizing the zipped standard library and removing pyd extensions and DLLs that your application
The generated "hello.c" is large and not particularly easy to read, but here are some snippets [...]:
