Cabinet door construction

Just wanted to hear what methods people have used to construct cabinet doors --- either for the galley area or inside. I notice diverguy has the side rails of his doors mitered and they look pretty good. I want mine to have an inset panel onto which I'm going to affix those old metal signs that you can buy almost anywhere these days. For the galley I have three signs of the same size that I'm going to incorporate but am as yet undecided on door construction.
