Pressing the close button usually causes the window manager to send the
WM_DELETE_WINDOW message[1], as described in the ICCCM. A short look
over the GDK source code didn't reveal a location where GDK _sends_ that
message. So GDK/GTK don't seem to support it. But you could have a look
at libwnck, which should have a working implementation for that message.

Ciao,
