Whee, I'm an alien! ;)

I'm not saying Tk is the best thing since sliced bread, I just don't
see what so many people seem to hate about it.

I have had no issues with widgets not working.  I will admit that the
widget set is fairly small, though.  You can get more from Tix (which
is also distributed with tkinter), but I haven't had any need for that
yet.

That's fair, and I agree that Tk should probably provide "close to
GTK" and "close to QT" themes for ttk[1].  As I understand it, though,
ttk gives almost complete control over the look of individual widgets,
so if you really don't like how your widget looks, change it!

Motif is indeed ugly, but your search for 'tk linux' doesn't tell me
anything about 'ttk linux'.  I would be interested in the results of
the script below on Linux, which I may or may not be able to try for
myself later (but can't right now).
