I agree. About the only real differences were: the choice of C++ as the
language, and Qt putting bread on the table of Trolltech employees.
GTK didn't ever directly contribute to a corporate payroll AFAIK.

At least Qt has corporate backing of Nokia. They have recently reasserted
that they consider Qt a strategic asset and that they plan their UI future 
around
it. Unless Nokia decides to throw out tens of millions USD worth of running,
debugged device code that runs on Qt, I don't see Qt disappearing any time
soon (famous last words, I hope not).
