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

Your best bet would be either wxPython or Qt, although I'd lean strongly towards wxPython based on my previous use. Both of these have fairly good fidelity on both Windows and OSX and feel and look like native applications.
GTK has marginal Windows support and pretty bad support on OSX. I would recommend against it.
cross platform gui..which tool to use?
