I encountered a similar problem with GtkAda - rather low level
and the marshalling stuff needed careful study each time I came
back to the package.

So I started writing "Simple_Gtk", code available here:
http://www.ramatthews.free-online.co.uk/

I haven't worked on it for a few months so have not tried
it with the latest GNAT - and so have not used the latest
Ada way of interfacing to C code. However it worked (it
includes test code) and covers a number of the widgets.
Perhaps it will give you some ideas.

Robert.
