What does Guido want in a GUI toolkit for Python?

[laplacian42 at gmail.com]

I just read a blog post of Guido's
http://neopythonic.blogspot.com/2009/06/ironpython-in-action-and-decline-of.html
and notice that he doesn't comment on what he wants in a GUI toolkit
for Python.

I sorta' wish he'd just come out and say, "This is what I think would
be suitable for a GUI toolkit for Python: ...". That way, someone
could then just come along and implement it. (Or maybe he's said this
and I missed it?)

So, what *does* Guido want in a GUI toolkit for Python?
