I wonder if PyGTK is as portable as Tcl/Tk...

GTK does not run natively on osx, tcl/tk does.


p.s: there are some ways to make GTK run on osx, like running it using 
the apple x11-server, but then it looks ugly and does not have the 
'native' feeling, or try to make it run with the gtk-osx port, which is 
incomplete :)
