Newbie question about running Python via GUI on OSX

[Larz60+]

and I was hoping to get a working solution

working solutions are created by programming languages, python being one of them.
If python presented 'working solutions' it would be considered an application, not a programming language.

By OSX GUI, am I correct in assuming that you mean Aqua?

if so, the python community offer the following 'packages' (for subject aqua): https://pypi.org/search/?q=Aqua
All (or most) of these include the source code that created the packages. That is (usually) stored in a repository named GitHub, you can see the source code for each package, by clicking on the Homepage link on pypi.

If you like what you see in a package, you can (again usually, as some installs are a bit more complicated) install using the 'pip' sample pip install aqua for any other package just replace 'aqua' with the (pypi) package name.

If you'd like to study the source code for any package,

1. First Install git (if not already installed):
   • Check to see if already installed: git --version
     
   • If not, follow installation instructions here: https://git-scm.com/book/en/v2/Getting-S...alling-Git
     
2. Now, from command line, navigate to the directory where you would like to place the source code
   
3. On the package GitHub page (get there by clicking Homepage in PyPi) you will see a green 'Code' page.
   • Copy that link
     
   • from command line, type git clone
     
   • paste link to end of line above and press enter. All of the code will be copied to your directory
