I make my own panels too and it certainly is challenging. I have bought the real dzus fastners from nick at aphs a while ago. and these fit into drilled holes on my sprayed mdf panels. Then for labelling i use letraset for white lettering a cheap way to label panels by rub on letters. then a gloss is used to seal the letters from accidentally peeling off. then i add whetever switches buttons etc i need and wire them up.
take a look at the gallery i posted a picture of one of my homemade panels last week - i'm pretty pleased for what it cost me to the real thing!
