outlook express question

i was wondering if it's possible to copy a botton in outlook express, the "send message" one for example, and place is in the desktop or in the control bar on the botton or anywhere else.
In particular, I'd like to program my mouse in a way that the right bottn will send a message, my mouse is programmable so I can do it, the point is that i don't know how to export the bottons from outlook express.
thank you!
