By Go program I am assuming that he means a computer version of the Asian game Go that has a decent AI.
As far as I know, it is very difficult to create a good Go AI because after the AI moves the player could make such a multitude of possible moves that it is nearly impossible to compute a good move in response without taking all the time left in the universe.
