When writing with GTK program, it would be normal to use a C style
cast here instead of a C++ one and write '(GtkFunction)GetAlarms'.

Of course, you might want to avoid the cast altogether and
let the compiler tell you that you got the prototype 
for your callback wrong :-)

                 ^^^^^^^^^^^^^^^^^^^

Where did this parameter come from? Why would a timeout
take a button button parameter?

Remove this parameter and add a gboolean return value
(TRUE = call again, FALSE = remove timeout), and 
you won't need the cast, and things should work better.
