label1 should be a field of your toplevel widget (window or dialog), so you'll be able to work by using 
object_connect and passing your toplevel widget - and in the callback, convert the parameter to your widget 
and access the field directly.

Also, note that recent versions of GtkAda support glade3/gtkbuilder.
