There are lots of ways to do this.
You could get at them through the container use 
gtk_container_children(myContainer)  
this gives you a glist of the children. Doing this is a pain as if your
ui changes it'll break.

If your using glade the simpleist way is just to use 
lookup_widget(myApp, myWidgetsName)
if your not using glade then either:

use the  userData bit of the callback (if you want to to pass more than
1 argument just stick them in a struct)

stick a pointer to them in the instance struct

attach them to a convinent object with gtk_object_set_data

i'd stick a pointer in the instance struct but it probably dosn't matter
much.

hope this helps
