Ah you're right, it seems you can get a static build by recompiling GTK+ and its dependencies with the appropriate flags and some extra manipulation... See http://wiki.inkscape.org/wiki/index.php/CompilingStatic for an outdated example. I don't know if that would work on Windows, it used to be not supported: http://readlist.com/lists/lists.sourceforge.net/mingw-users/...
