The function 

vtkObjectBase *vtkPythonGetPointerFromObject(PyObject *obj,
                                             const char *result_type)

is defined in Common/vtkPythonUtil.h

Simply pass this function the Python object that corresponds to your
Python vtkRenderWindow and the expected return type ("vtkRenderWindow"
in this case) and then use the returned pointer (after suitably
typecasting it of course).
