Disply posts in all three columns-- plus, ideally, a widget or two, too?

My Q is the same as "reallylost's" June 02:

"is it possible to display posts (excerpts and image with link to full page) from category A in the left sidebar, posts from category B in the center, and posts from category C on the right sidebar?"

We have 3 prolific editors who want to update 3 separate columns on the front page, linking to their separate Category pages for the full stories.

Atahualpa looks like the best possible theme for that, but i'zat possible?

Thank You.
