Not one Pokemon can have 4 stages of evolution. I've never seen one either. But, it could probably be possible to use a hack, such as GameShark. I don't know how to use it, but it is possible.
Again, no Pokemon has 4 stages of evolution unless you hack your game.
The highest number of evolutionds I've seen is 2.
