Writing nothing in Python!

It is one of [lack of] education that leads people to develop GTK or Qt in
the languages like C and C++. If you looked at GtkAda and compared it to
the native C API you would immediately see how much safer GtkAda is. E.g.
you could not connect to the "clicked" event of a tree store. That would be
a type error checked statically. [You still could work around that and
proudly get a run-time error from GTK]

I suggest writing everything in Ada.
