This is a start.  I'm new to 6 so hopefully others will post better solutions:

DynamicModule[{pts = {{0, 0}}}, 
 Row[{LocatorPane[Dynamic[pts], 
    Show[Graphics[{}, PlotRange -> 5], Axes -> True]], 
   Show[{Graphics[Dynamic[Point@pts], PlotRange -> 5], 
     Plot[Sin[x], {x, -5, 5}]}, Axes -> True], Dynamic[pts]}]]
