Help. homemade jukebox keyboard

Hello everyone.

I decided create a homemade jukebox for my parties
the more I investigate, the more things match.
I originally was gonna use another program designed to create what I want. I was reading about and I found XBMC. and I said, I'll take it
I want to make the XBMC menu options only music, karaoke, music and videos. eliminating options and settings buttons.
everything is perfect. exept this ... the keyboard.

I would like to be able to handle everything with one of these keyboards

another thing I've been thinking about is the virtual keyboard.
I do not know if it is possible to change the virtual keyboard window. for any pop-up like this:

[0-9] [A] [B] [C] [D] [E] [F] [G] [H] [I] [J] [K] [L] [M] [N] [O] [P] [Q] [R] [S] T [U] [V] [W] [X] [Y] [Z]

horizontally. and navigate with the buttons forward and back.
another thing I've thought a lot. is that when you press the D key for example, display all artists starting with the letter D. and not all music files that start with the letter D.

guys could help me with this?
