Comment 632 for bug 1

This is relatively easily done with software libre, but as for proprietary software, most of which will never be ported, you can always use Wine ("an Open Source implementation of the Windows API on top of X, OpenGL, and Unix. Think of Wine as a compatibility layer for running Windows programs."), which should hit version 1.0 by summer! (June 6 appears to be the goal)

Please see:

Once Wine 1.0 is released, it would be nice to see an organized push towards getting companies to test against it. Even if they aren't going to release a native port, something that *works* under Linux would be a nice step (consider Google's Picasa software).
