swf virtual piano + scores player

Hello,

For my "How To Play Piano" website I am looking for
exactly this: http://www.zebrakeys.com/swf/advanced/learnsongs/hark_the_herald_angels_sing_both_hands_pl ay_424.swf

I am not a programmer / coder but a musical amateur.

Please advise how such a thing can be created. Here is another example:

Thanks.
