GTK can run on windows too (see Gimp for Windows, Gaim, etc).  The main
difference is that Qt is a C++ framework (and a nice one at that), while GTK
is a C based one.  My wild guess is that most people today prefer to write
in C++ vs. C.  And C++ programmers will always prefer to use a toolkit that
is compatible with C++ idioms.

The other major difference between the toolkits is license: Qt is QPL/GPL,
GTK is LGPL.  That means you can write closed-source apps with GTK, while
you need to buy a license from TrollTech to write closed-source apps in Qt
(writing GPL apps in Qt requires no additional license).  But for little
front-end clients, the license issue probably doesn't come up.
