Why is Python popular, while Lisp and Scheme aren't?

If you release under GPL on free OS's, you can freely use a Qt
version that is, indeed, "pretty decent".

If you release under other licenses (not sure about other non-GPL
open source licenses) or for proprietary OS's then I think the
non-commercial versions you're allowed to use are variously crippled.
Basically, if you and/or OS vendors are profiting, trolltech
wants a slice of the action, too;-).
