Buy some expanding insulating foam and carefully spray it into the gaps. Remember that it EXPANDS so you don't need a lot. Make sure you buy the type for windows and doors because the other type will expand with force and put unnecessary pressure on the sides.
It's best to do everything at once because the can is useless if you go back and try to use it later.
Once it's set, trim off any excess with a knife and replace the trim. You should be able to hammer back the original nails but if not, you may have to re-nail. Some people use double-sided tape if there is nothing to nail to.
That should help a fair amount for the $$ invested.

Thanks I'd never thought of using foam. I should post pictures of the windows.. the place is 100 years old, and the windows swing closed and lock on the tops and bottoms. So there's no trim at all, just a wood on wood 'seal'.
