No, Python is not released under the GPL and there are very few restrictions on redistributing it. See

AFAIK you can license your *scripts* in any way you choose.

Tkinter (included with Python) and wxPython are both popular for this. The general consensus seems to be that Tkinter is easier to use for small projects while wxPython is more complete and better at creating apps that match users' expectations of look-and-feel.
