Creating an itunes web player

Does anyone know how to create a web player similar to this:

Im trying to create one similar, but isn’t all the way fancy, it just plays the music, I just want it to have a playlist, volume, stop, next track, previous track, and a picture for each song.

i dont really have a clue how do this. So far i created a 1600x1000 skin completely similar to the link above, now i just need to know the right coding for the buttons, and how can keep adding music every 2 weeks. and tommorow (which is in a couple hours), i will have a chance to work with cs4 in a studio.

all help is appreciated.
