I guess the answer also depends on weather you want to be kewl and boast that you cross compiled or just get working stuff. I run a windoze develepment machine in VBox. That way it is easy to do and you can make use of existing packager tools that are windoze bound. That said I make the occasional package for win using Qt that lets me do mac/linux/win from the same source, but I do very little win stuff.
