It's only possible for jailbroken devices. Apple has no public APIs that allow you to display things other than push/local alerts on the lock screen or home screen.

This is not possible using the iOS SDK. It may be possible on a jailbroken device, but there is a 0% chance that it would make it into the App Store.

Is this possible?

Nope
