send SMS from a WM 5 - 6.5 smartphone using a button

Hi,

How can I send SMS from a WM 5 - 6.5 smartphone just by using a button?

I want to send the same message from one button, without having to enter the text message every time.

I have 20 different text messages to send, and they NEVER change.
So I want to create an app with 20 buttons to send each of them.

Has anybody got a sugestion, or an example code?

Thanks.
