Python3-friendly UI based on wxPython
CHIRP has historically been built on pygtk, which is not available in Python3 and never will be. Python2 is deprecated and will eventually be unsupported on major platforms.
In order to facilitate a move to Python3 for the core of CHIRP, something has to be done about the UI. The pygobject libraries provide an imperfect compatibility layer, but support seems rough and stability is suspect.
This issue is to coordinate the work on a UI re-write using wxPython, which is well-supported, long-lived, and generates native widgetry on the big three major platforms.
