[pygtk] How to make Outlook style toolbar?

[Jonathon McKitrick]

Does anyone know how to make an Outlook style toolbar?  I think Mozilla has
one as well.  It's the big icons stacked vertically.  Ideally, I'd like the
extra little tabs at the top and bottom that expand into new subgroups when
clicked, like this:

--- group ---
--- group ---

    icon

    icon

    icon

--- group ---
--- group ---

Each group, when clicked, slides up or down and reveals other buttons/icons.
