   A modal window is a window that, while being displayed, blocks all
other widgts that don't belong to that window, so the user can't interact
with any other part of the interface of the same program.

  Yes, but you have to use the gnome-libraries. Gnome has a
gnome_dialog_run function that blocks and only returns when the user has
pressed a button in that dialog. 

  If you don't want to create/destroy the dialog all the time, you can
call gnome_dialog_close_hides to set the dialog to just hide the dialog
instead of closing it.
