I use wxPython.  I couldn't get PyQt to even work, much less to develop 
with it.  Other people have said the same thing about wxPython, so 
perhaps it is a 'depends on the user' thing.

I am not a lawyer, but here is what I believe to be the case:

If you modify a piece of GPL'd software and distribute it, you must 
distribute the source of the modified GPL'd software.

If you /use/ a piece of GPL'd software to create 'something else', and 
the 'something else' gets distributed, you have used the GPL'd software 
as a tool - and are /not required/ to license your 'something else' with 
the GPL.

Corrections always appreciated,
