I have taken the time to put together one of our button packages (Green) into a .zip file. I know there have been a couple people unable to get graphics work down, and could use just basic buttons for an addon interface. It's only 63kb, and the link is:
(63kb) PNG:

(14mb) JPG:

It contains just a few buttons that will hopefully help add to a basic interface. The person who created these is available this week for creating graphic work by request. Simply send a Private Message on these forums to me, or add him on skype as Immortalmage2 (He's online often).
