If you already have apache, mysql ... installed then they can be started / shutdown via standard linux commands.
All webmin would do in this case is to run those commands when the 'Stop MySql' button is pressed.
You keep the same installation of your current apps and just install webmin as a separate admin app.
But if all you want to do is to stop and start your apps then either use the command line or an xampp gui.
