python +gtk? is that a serious statement? Is there a way to do quick mockups of GUI screens or are you just stating that python is good for rapid development?

Thanks Bundyo, THIS ROCKS!!!!!! I'm getting teary-eyed already. I've spent so many hours fumbling with MSPaint and Powerpoint to mock up interfaces. This could be a life saver for me. Well, at least I won't have to bring so much work home anymore.
