Dicom and three planes

Hello, i trying to create dicom viewer with three planes like in photo

I find example - Medical/MedicalDemo3/ - but it in 3d style. Another example to difficult for me https://vtk.org/gitweb?p=VTK.git;a=blob;f=Examples/GUI/Qt/FourPaneViewer/QtVTKRenderWindows.cxx
i intersting how to create 2 planes (sagital, coronal) with crosshair on front slices (images).
https://vtk.org/doc/nightly/html/classvtkResliceCursor.html - this is right choice four this purposes?

VTK examples are primarily for education purposes. If you need a functional medical image viewer then the most efficient way to get there is to customize/extend an existing open-source viewer, such as 3D Slicer or MITK.

This is more difficult, i trying to understand what class i need use to create crosshairs on dicom image.
