Kevin,

A cheap way to approach this is an easy-digi soundcard (search ebay for the kit) and a USB to serial adapter for PTT. The two components together will accomplish what you want at a fairly cheap price. They also offer prebuilt easy-digi for a bit more $$ but I have no experience with the prebuilt ones. I built the kit and know it works as I ran an APRS digipeater with these two components and a Baofeng when I was first starting out. I also remember that it took me forever to figure out the correct wiring. I wish I still had the notes I made but don't seem to be able to lay hands on them. Hope that helps a bit. Good luck with your project.
