Check out helloworld.c in the examples directory in your GTK distribution.
Essentially you have to attach the "delete" signal to a function that
returns a gint.  If you return TRUE, clicking on the X will send the
"delete" signal, but GTK won't actually delete the window.

If you still want the window to close, simply call gtk_widget_hide in the
same function, and the window will go away (to the user) but a subsequent
gtk_widget_show will bring it back again.

Hope this helps.
