There can be address of memory or any value
  ( LPVOID ) 0x12345678
and messages WM_NCCREATE, WM_CREATE receives in lParam
structure CREATESTRUCT address, where member lpCreateParams
have value passed through lpParam in CreateWindow(Ex).

Have you experience on this?

lpCreateParams can be used to pass windows structure/object, but this does not help if you want to have hWnd and windows structure binding in WM_GETMINMAXINFO, since this message does not have CREATESTRUCT parameter. WM_GETMINMAXINFO processing could be useful if window size should depend on its child controls size and you want to avoid flicker caused by multiple resize.
