Create a structured points data (or structured grid if that does not
work) with constant Z and treat your given z values as scalar
attributes at each of the points on the plane. Then use the
vtkWarpScalar class to warp the plane using the scalars to produce a
carpet plot. Use vtkPolyDataNormals if you want a smoother
appearance. Use vtkCubeAxesActor2D for the axes. That should get you
started.
