Greetings Brad,
Getting native windowing support to work with Tcl/Tk, or Python/Tkinter, 
or Python wxWindows requires that the script is started by drag/dropping 
on a GUI version of the interpreter, or (in the case of Python2.3) 
starting from the command line while explicitly specifiying the GUI 
version of the interpreter (pythonw script which points to python.app).  
I don't really use Tcl, but there should be a "Wish Shell" icon in the 
utilities directory in Applications.  Try dropping a Tcl/Tk VTK example 
on this icon--a GUI interpreter will open and you should be able to give 
focus to Tk windows.  This is some wierd thing with Quartz--you can't 
seem to start native windowing applications from a command line 
interpreter yet.
   If you build Tcl/Tk and/or Python/Tkinter for X11 things will work 
normally in the X11 environment.  If you want to start a Tcl/Tk Carbon 
application from a terminal window, you may be able to do so with a 
command like "wish8.4 vtkapp" (rather than "tclsh8.4 vtkapp") if your 
display environment variable is configured correctly.
