Extra note:

I wrote this code off the top of my head, there is a good chance it will not
compile the first time.

I expect you to search gnome.developer.org and use the appropriate GTK+
apis for your needs.

Please inspect the GtkEntry apis and GtkPaned apis yourself and try compiling
it yourself.

Cheers,
         -Tristan
