making it as a regular 4:3 ratio, it might be a bit tricky. If you are trying to create one out of my template, theoretically it is possible. I would take a screenshot of the stock main menu in res 1600x1200 and work from there. Or take the original main borders that's included in my template, and stretch it to 1600x1200 resolution and start editing from there. I like to work in the correct ratio first and then stretch it to the red line so what you see is what you get. After you are done, just make sure you stretch it to the red line and it should look correct. Of course I never done this, I'm thinking off the top of my head.
