Convert + Extract .deb & .rpm on windows

Is there a way to convert between & extract files from *.deb & *.rpm files using a windows machine? Is there a tool available that can handle something like that?

I have a floppy based firewall at home & want to add some programs. But I can’t install rpm or debian package mgr on the firewall (space constraints). And I don’t really want to mess around with a vmware or a full installation of linux. Just looking for a quick solution.
