Exact behavior is a bit window-manager-dependent.

GTK_WINDOW_POPUP is for menus and tooltips, not "normal" windows, it
will behave very oddly if you use it for normal windows. Notably these
windows are not window-managed.

Some window managers will handle GTK_WINDOW_DIALOG a bit differently,
I think because GDK sets the window transient for the root window.  To
get optimal dialog behavior you need to call
gtk_window_set_transient_for() to set your dialog transient for the
appropriate application window though.

Normally you always want GTK_WINDOW_TOPLEVEL, because if you want
dialog you're using GtkDialog or GnomeDialog and if you want 
popup you're using GtkMenu or GtkTooltips. So if GTK were being
designed from scratch today I'd say the argument to gtk_window_new()
is fairly pointless.
