Can you click on a desktop icon and play a .wav as well as starting the app?

The question is as in the subject line.

Is it possible to set more than one command on a desktop launcher? For 
example, you have a music app and want to play a few bars of music as the app 
is launching when you click on the icon. Is that possible? 

If so, how would you set this up?

I've no idea if this is possible, but perhaps the linux guru's out there might 
know.
