Copernicus is a G, the unibomber coming in as a close second.

Andy Warhol (Warhola really) is from The Slowakei which is really more of a Czech state than Polish.

None of the above.
Only three names come to my mind at the moment: Zbigniew Karkowski, Rafał Księżyk and Marcin Dymiter.

I voted for Chopin. Big surprise.

Erm.....Andy Wharol wasnt polish!
