Nobody is going to write your code for you.

You're writing two applications for this. One for the Arduino and one for the PC. The two are going to communicate over a serial port. The Arduino has to send its state data over the serial connection to the PC. The PC then has to listen for that data and parse the data it gets and updating whatever display you provide for that state.

Seriously, if you're new to programming, writing code for a microcontroller is NOT the way to learn. Learn how to write code first, small applications on the PC and whatnot. Move to microcontrollers later because you're going to be adding a couple layers of complexity to writing that code.
