Tcl/Tk happens to be a good GUI toolkit for making cross-platform apps that appear native on each platform.  From my point of view, we should just implement things better, changing the GUI toolkit is not going to make as big a difference.

Matju told basically the same so i'm convinced. No Alexandrian solution hhhh :)
Actually, do you consider the GUI or the GUI-core communication "slow" (ie a large performace potential in optimizing), or is just that we overdrive it sometimes? (Or is it like "smooth or not smooth"? ;o)
