I am not aware of a binding to Qt.  Generally, binding to C++ from
another language is difficult, because this requires knowledge of the
compiler's name mangling scheme.  Also, some C++ features do not map
well to other languages (templates in Pascal; multiple inheritance in
Ada; etc.).  By contrast, GTK+ was written in C for the specific
purpose of making bindings easy to write.  The GTK+ developpers
recommend against using C for applications; they recommend using one
of the many language bindings instead.

No, you can learn just GtkAda.  Occasionally you'll need to look at
the GTK+ reference manual.
