Subject: Add some minimal GTK+ love to kub
X-Git-Url: https://git.cworth.org/git?p=kub;a=commitdiff_plain;h=37bb3dc4133f4317de3b00423fea6778248c27ca

Add some minimal GTK+ love to kub

This initializes GTK+, creates a window, and establishes 4 callback functions
for handling expose, key press, and button press/release events. So far,
the callbacks are just printing things to stdout and not really doing anything
useful yet.
