To tell you the truth I never used lookup_widget. I only delete the
declaration of main window in main.c, I created a file with all global
variables and I declare them as extern in callbacks.c, so I can use them
every time I will, and I can retrieve data about all widget associated
with them, but I think that your idea is good.
