Whatever you do, don't build a cabinet and then put a pre-built commercial panel on it. Nothing looks worse than a cabinet that should be your own uglified with something that everyone knows you didn't build. If this is an existing cabinet that you are just maming, it'll look doubly worse.
Building the control panel is perhaps the easiest thing to do. If you can drill a couple of holes, you can build the control panel. The arcade encoders such as the IPAC and Keywiz are super easy to use.
I suggest you have fun with your little adventure and do some searching on this site for the topics you want such as wiring an ipac, building a control panel, templates......etcetera. This site is a wealth of information that we couldn't possibly dictate for you.
