I am looking for a GUI toolkit for Python 3.2 that looks good on both Windows 7 and OS X. Here the catch: I am at best an average programmer so I need something really easy to use. My program will not be too complicated: I would just use listviews, buttons, text fields, etc. Is creating the GUI widgets via an XML file (along with the layout) a good way to go these days? It seems like this would be easier to develop and maintain.
Right now, I have a good command-line version of my program and want to add a GUI to it. I'd also love to "compile" the Python code and then be able to distribute it a .exe installer or a .dmg image.
Any help would be greatly appreciated. Thanks!
