Short throw (distance) projection

I need to project from a 15" or 17" LCD to 60" screen from 60 cm distance. What optical setup i must use to achieve my goal?

Wow! That would require a VERY short focus and very large lens. If they exist at all, they will have quite some distortion. And/or be VERY expensive. I don't think it is doable, unless you have unlimited (military) funds.
