rb2c may help you.

Try profile.rb in the standard library.

  ruby -r profile your-script

Use inheritance, just like in other SI language, to represent is-a
relation.  And if a set of function provide features that can be
shared among classes, make it mix-in.

I hope Ruby/Gtk become mature enough soon.
