I would suggest starting by looking at the "changed" or "insert-text" signal for the GtkTextBuffer.

When you get called back, you can then set the tag.  

When the user changes the tag in the menu, I would say the easiest thing to do would be to update the TAG 
properties.  Another approach is to simply have GtkTextMark's in places which you want the selected tag to be 
applied, and simply use gtk_text_buffer_apply_tag_by_name() and gtk_text_buffer_remove_tag().
