That's not really how this works. What have you tried? What have you googled? Did you find anything that doesn't make sense? Did you attempt to write any code? What worked, and what didn't work? How didn't it work? Be specific, and post runnable code that demonstrates where you got stuck.
We can't really answer general "how do I do this" type questions other than to direct you to the basic tutorials and google. Ask a specific question, and we'll go from there.
But chances are you should probably try something simpler, if you have no idea how to even start.
