Help with a problem

Hi, I was assigned an extra credit problem that I have no idea how to do, I was wondering if you could give me some example code to do this (Using openGL):

it needs to have the borders, different colors and directions. Thanks!

P.S. I know there are the instructions there but I don't understand them. Thanks!
