I'M SURE THAT I WANT TO REINVENT THE WHEEL Sometimes current wheels are ain't good for me.
Can you put me on a start up line. I used to be a married to M$ ".net developer", and I'm in love with gOOgle.

As Emmanuel has already stated, it is not possible to truly replace the phone app without recompiling the operating system. Even on a rooted device, you are still locked into the vendor firmware and trying to work backwards from there would be a tenuous proposition at best. Now, it is possible to receive notifications in certain event types and preform actions there, but I doubt this is what you want to do.
However, for those who must know what goes on under the hood, take a look here
For exposed telephony interface (including SMS API), see android.telephony

It's not possible to replace the phone application besides making a custom operating system and install it on rooted phones. But that's a lot of trouble.
But you can develop a separate application and have it make phone calls or intercept incoming calls. But while the user is talking on phone he'll still see the old phone application.
