TileMill available for Windows, too
I just got news that TileMill now also runs on Windows (besides Mac OS and Linux). TileMill is a browser-based tool to prepare map tiles which you can, for example, overlay on Google Maps or use as basemap in a Processing sketch. The latter of which I have in my ZIPScribble maps series (here, here or here; some background on using TileMill with Processing can be found here and here).
