vtkRenderWindow::SetCursor( VTK_CURSOR_CROSSHAIR );

You'll need to use VTK CVS or VTK-5.2. (I think it made it to the 5.2 
release) since I added it recently.

One issue is that the crosshair is that on X11 the crosshair gets 
rendered as a big fat plus rather than a crosshair. It pretty much looks 
like XC_plus (see http://tronche.com/gui/x/xlib/appendix/b/). On Windows 
the cursor looks good.
