This might be a help:

http://www.bygsoftware.com/examples/excel_addin.htm

It contains a workbook download that shows how to create an interactive
add-in controlled by a toolbar.
The toolbar is created when the add-in is loaded, and deleted when the
add-in is closed.
The code is open and commented.
