i need One big button

[nerofutura]

I have a problem using my pocket PC - i often use it to listen to music on my motorcycle which means it is in my pocket - i want to use voice command to change the music but can't hit the hardware button to make voice command turn on - so i was thinking - if i had an app that turned the screen into one big button that turned on voice command i could just touch my pocket and it woudl work...

so what i need is an application that launches voice command from a big button on the screen (the whole screen becomes a button) but locks all other buttons - some combo of two harware buttons coudl close the big button launcher. - anyone up to playing around with this a bit since i have no idea how to program.

if you build it the idea is yours...or if you know of somethin like it please let me know.

thanks
