If you want to go the Arduino route, you can use the LiquidCrystal
library to hook up the LCD screen.
http://arduino.cc/en/Tutorial/LiquidCrystal It requires 6 digital
pins, so there should be enough pins left for the switches/relay. You
can even go cheaper by using something like Metaboard where USB is
done on the ATMega instead of on a dedicated chip.

your own board, this has the added benefit of not requiring any
surface mount soldering.
