Yes, use one of the vtkAbstractPicker subclasses

Check the picking code in vtkInteractorStyle::OnChar() for a starter.

This has changed, you can now use the whole interactor and interactor style 
framework within Tk, through the use of a vtkGenericRenderWindow. All Tk 
bindings as well as the Tk examples have been updated to reflect this change

Bindings;
         VTK/Wrapping/Tcl/vtkinteraction/
Examples
         VTK/Examples/GUI
as well as all Tcl scripts using vtkTkRenderWidget (see Examples and Tests 
sections in:
http://public.kitware.com/VTK/doc/nightly/html/classvtkTkRenderWidget.html

Hope this helps
