ready to use python, need help with GUI decision

[simo]

If you've got some money to buy a Windows commercial license, or just
want to program for Linux/GPL, then I'd say go with PyQt. The only
thing that puts me off is the stupid licensing issues which even the
PyQt/Qt/BlackAdder folks don't seem to grasp.

If you don't want to pay anything and go with whatever license you
want on Windows/Linux, then I'd say go with wxPython. What puts me off
is that some of the dialogs are completely different between OSes, or
have limited functionality on Linux.

If you don't really mind how it looks and don't need a wide range of
widgets and just want something easy, I'd say go for TKinter.
