He already told you he used Gnome Canvas.  He already showed you a
link he found from Google.  I suggest you start doing some independent
research from here.  You've been given many very good starting points.
 What else do you want us to do, write the whole application for you?

Stop thinking in terms of your existing C++ graphics library.
Graphics does not work like that any more.  Pick a graphics library to
use, and read up on it.  This example was in Gnome.  Join a Gnome
mailing list.  Read tutorials on Gnome.  Buy a book on Gnome.  However
suits you.
