Terry, thanks for helping put this more clearly.

I'm fairly enthusiastic about PyGUI for this purpose, but I'll happily
throw it out in favor of a better candidate.  The goal is to get a
good standard GUI system included with Python.

Sure.  I see wxPython and the others as potential implementation
platforms for PyGUI, rather than as competitors.  We might have
bindings for PyGUI for each of them.
