More or less.  You will need to ensure that when the window is finished
with you have called gtk_object_destroy() or gtk_widget_destroy().  I
suggest you also read the documentation, which has an example:
http://library.gnome.org/devel/gtk/stable/GtkDialog.html#GtkDialog.description

If you want this, then why not call gtk_dialog_run() and have a
blocking dialog?  However, if you have a special reason why you want to
do it without a recursive call to gtk_main(), then use
gtk_window_set_modal() as well as gtk_window_set_transient(). As a
further sophistication you can set the parent insensitive with
gtk_widget_set_sensitive(), but if you do that you will need to set the
parent sensitive again when the dialog is finished with (say by
connecting a callback to the destroy and/or hide signal).
