Please note: this is not a direct answer to your question.

I would personally go for a client-server model; not worrying what the
server is written in or how it works. For some reason I have a scary
thought of your widget pulling in 100million records and cross-tabbing
two dimensions :) Don't worry about python bindings or such, why not
try and find something that can take an OLAP query, maintain
aggregates/computations on a DB that can possibly return in XML/JSON/
WHATEVER then just have your widget render visually the response and
send out XML/JSON/WHATEVER on click events.

Basically your widget is a renderer and UI to update the MDX/whatever
instructions in the OLAP server.

Of course, for small datasets, just nested dicts-of-dicts rendered
would probably do.
