network mapper Gui question

[kyle.tk]

I am trying to make a program much like cheops that will make a
graphical representation of my network. What would be the best language
to make the actuall interface in, Tkinter, wxPython, PyGtk? And in
those what module would work for something like this. It needs to be
able to redraw it self about every half minute or so without being to
heavy on the processor. Any ideas?
