Help me with creating Pacman

How do i make ghosts move at the same time as pacman?

My group (where i'm the main programmer and logic guy) has decided to re-create Pacman..... i've got the basics down and everything but the main problem is how can i get the ghosts moving at the same time while the user controls pacman???? Also, if the player makes pacman to stop moving (meaning he reached a corner or an edge) the ghost should move too..... How can I do that???? Thnx in advance
