How do I create an ILS?

Sorry if this has been posted before, I tried my best to look for this topic, but couldnt find one.
Anyway, I was just wondering how to make an ILS for say a small airport (PAHN). I would perfer to use AFCAD, but if I need a different program I would be happy to get it.
Thanks in advance
