While it lacks a user-friendly installation process, I've had a great experience so far with running the windows version of steam via the game-porting-toolkit. I just run gameportingtoolkit-no-hud ~/my-game-prefix 'C:\Program Files (x86)/Steam/steam.exe' and a whole bunch of windows-only titles just work.
