AFAIK there isn't a way to do this out of the box, so you have to do it in code. This discussion at Microsoft's TechNet forum talks about some free and pay tools that address this need.

Then again based on your needs you might be able to do something with web forms, i.e. create a form to edit those items that allows one group to edit all fields and another group to only edit some fields. It's cumbersome since you'd have to create a form for every list you need to restrict at the column level, plus manage permissions, but with this at least you have a functional workaround.
