 This was discussed a lot of times. In short, you can't (you'll have to
implement window manager in order your app look like MDI in windows). Read
archives of gtk-list.
 If all you need is "that any operation on the parent window also affects the
child" then you can use window groups for that (there is a concept of window
leader for given window, when leader is moved, all windows for which it's the
leader are also moved, same for minimization and iconification).
 Not all Window managers support it - but recent enlightenment (definitely) 
and sawfish (probably) support it. All you need for setting window leader for
particluar window is to call 

void        gdk_window_set_group            (GdkWindow *window,
                                             GdkWindow *leader);
 (note - args are not GtkWindow)!
