Volume rocker as next/previous song

This probably is a common question but so far I have not seen a thorough answer. I want to know if it is possible to have the rocker functionalities that are on cyanogem mod on a factory rom (htc desire s). that is: long press up = next song. long press down = previous song. short press up = volume up short press down = volume down I would like to keep using the HTC ROM, since I like the sense UI, and also id like to keep using the HTC music player, I think is simple and is able to manage correctly the compilations albums. Does anyone know of an app that can do this, that is NOT another music player. Or as a 2nd option to explain if it is possible to create my own app for it and maybe to make some points towards the right direction to do this.
