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

As Matt already suggested, wxPython should be the most portable choice. On Windows it uses the native GUI toolkit, on Linux it will use Qt as backend (I dunno what it does on OSX though, but you can probably find out all of that on their website).
cross platform gui..which tool to use?
