I'll even help you put together the skin. Do you have pictures of the cabinet? I'd love to see it...
You'll need to save two of the buttons for next page/previous page, and you may want other buttons for optional functions like a button to show the most popular songs, a pause button, or a button to skip the current song. Presuming you use a "popular" button and a "pause" button, you can use the remaining six as letters A-F and numbers 1-6, giving you 36 selections on the screen at once. The testskin.ini skin is very basic-looking, but it is formatted for 36 selections, and it'll give you a chance to try out the software right away; it can be made to look better later.
