The Arduino really is the best and easiest solution for that. It would be fairly easy to write some firmware to take in serial commands to operate relays or read inputs. And since you already have one, it's cheap tooGet a couple of ULN2803A's and use them to switch the ground on a relay on/off, and a couple optoisolators to read digital inputs and you're set.
Or you can take the easy way out and buy one of these:
