GUI in Python? wxPython?
I've used both wxPython and PyQt for simple apps. I started with wxPython because the documentation made it very easy to learn.
If you're new to programming GUI's or you just need to get stuff done quickly the wxPython Examples are amazing. The wiki also has a lot of examples, tutorials and how-to's. The PyQt documentation is much less satisfying for beginners in my opinion - it's light on examples and how-to's and heavy on API documentation.
