I am developing a python program (my native platform is Ubuntu) for which I would like to build a simple gui. I would like the GUI to be cross platform.I came across python-gtk/wxpython/qt.  What is the best tool to use? 
Thanks

I'm going to suggest tkinter. It's part of python, ridiculously easy to use, and of course is very cross platform.
Many people dismiss tkinter based on years-old knowledge, but tkinter has evolved a lot. Some say it looks ugly, but more often than not functionality and ease of use is more important. Tkinter is definitely the best pragmatic choice in my opinion.
That being said, however, there is no "best". Qt, Wx and Tk are all fine, all do pretty much the same, and are all more-or-less equally cross-platform. Pick any one of them and don't look back. Once you get experience with one of tnem you'll be in a position to decide for yourself which one is "best"
cross platform gui..which tool to use?
