Strange Question about Flatscreen Monitors

The situation is as follows. I have a Sony flatscreen monitor (don't flame me I know you don't like it but I do so neh ) and as far as I can tell it can only accept the montior cable that most computers use. What I would like to do, if at all possible, is to some how plug my game-cube up to my monitor. At the moment all I have is the standard red yellow white cable and I would like to know if it is even possible to find an adaptor that might be able to convert that into a plug my monitor can use I'm sure it could be done with a little work but I'm not sure how lol
