Your math is definitely rusty. RungeKutta techniques are useful for solving a known set of differential equations numerically. This does not give you a convenient way to figure out which set of differential equations will give you a known set of points. Worse yet, many sets of equations will give you those points, and RungeKutta offers you no way to decide between them. Thus while the similarity of certain keywords might make you think that there is a useful connection, there really isn't one. Sorry...
