The only thing you have to do to enable your class to work with vtkDenseArray is add a single line: 

operator vtkVariant() const { return vtkVariant(); }

CustomDenseArray.cxx

#include <vtkSmartPointer.h>
#include <vtkDenseArray.h>
 
struct Point
{
  double x,y;
 
  operator vtkVariant() const { return vtkVariant(); }
};
 
int main(int, char *[])
{
  Point point;
  point.x = 1.0;
  point.y = 2.0;
 
  std::cout << point.x << " " << point.y << std::endl;
 
  vtkSmartPointer<vtkDenseArray<Point> > array = 
    vtkSmartPointer<vtkDenseArray<Point> >::New();
  array->Resize(5,5);
 
  array->SetValue(4,4, point);
 
  Point retrievedPoint = array->GetValue(4,4);
  std::cout << retrievedPoint.x << " " << retrievedPoint.y << std::endl;
 
  return EXIT_SUCCESS;
}
