Installing and enabling fonts is pretty much just dropping them into a directory fontconfig knows about. Now as far as disabling certain (installed) fonts or switching rendering methods, specifying particular rendering methods for particular fonts, or specifying replacements for fonts you don't have installed or don't want to use -- those things do require editing XML dotfiles. But as far as I know, they can't be done at all on Windows (at the user or system-wide level; I think applications can do them for themselves).
