I'm no wx* expert, but I know some about Carbon.
In wxMac, wxWindow::GetHandle() returns a ControlRef which is the same as an HIViewRef.  ControlRef is the "old" style.
You might have problems using a wxGLcanvas with vtkCarbonRenderWindow, as both might step on each other's toes as they attempt to do OpenGL stuff.  A generic wxWindow or wxPanel might be better.
