My solution would be to create a folder called Woots and place short MP3 sound files in it. I would then put a shortcut to Woots on my Today Screen, using tdLaunch, freeware (CAB available at 2nd link below). Finally, I'd make it finger friendly so that it can be done 1 handedly, with thumb of the hand holding phone, by using GS Finder Plus. GSF+ is also freeware, info here:

Hope this helps, and thanks for the idea! Think I'll do this one day, time permitting.
PS: I have MP3s associated to TCPMP (GSF+ makes this easy) so as not to disturb current playlists in my regular music players, and to allow quick launching of a single request or perhaps soon, whoot sounds.
