objective-c/iOS Track location with camera

Question

I want to display real time video on the iPhone Screen. I know the GPS coordinate of my house.

I want to display a vertical line on the screen that shows me my house direction. If i move my phone, turn left, right, i want the vertical line to move left and right to show where is my house.

If my house is behind me, i do not want to see the vertical line.

Do you think this kind of application is easy to make ?
