I was citing the amount of work to create a minimal acceptable toolkit to a programmer on the street, the sort of toolkit you'd point a hostile Python programmer to to say "Yes, we have a native toolkit", not the toolkit that you'd use to convince an already-converted Haskell user. Bear in mind that Tk prior to their relatively recent theme work was not that toolkit either! And that was actually a pretty decent kit, with layout managers, a nice text widget, tabs, all the basic stuff you'd need, if not the fanciest ever.
