I'm actually not familiar with the PLplot-Gtk+ combination--I only
wrote the Ada bindings. I'm sure if you post your question to the
plplot list you will find out very quickly if the PLplot-Gtk+
combination has any synergy with writing GUI's in Gkt+.

Yes, Annex G is only a very small part. There has been an effort to
bind Ada to lapack but I'm up to date on it. Google "lapack Ada
binding" and I think you'll find some useful results. Let us know what
you find.

I would also like for there to be an Ada binding to GSL, the Gnu
Scientific Library:
