Ivan:

This is more of a GTK than a GtkGLExt question - I think you want to use
multiple GtkDrawingArea widgets for your main window and sub-windows,
and use a GtkFixed widget as the container.  The main issue will be
handling Z-order, which I assume is based on the order in which you add
widgets to GtkFixed.  With GtkFixed you will have to manage the sizes of
your widgets explicitly, e.g: when your main window is resized.

Cheers,
Tim
