If you are a beginner to wxPython, I hope this project can help you.

I’ve looked at most of the code and have yet to see a header, or really, any comments whatsoever. I also see that this “simple” project requires a dozen or so packages that I do not have. I would not recommend that anyone use this as a starter project. Nothing can be learned from undocumented code.
An appropriate starter project would be something that requires python and wxpython, and very little else.
