I know, it's a little outdated, but for the most part it's still o.k.
The parts that have changed since 1999 mostly affect a couple of new widgets
in the standard library (LabelFrame, PanedWidget, OptionMenu...) and some new options
that were added (like the "compound" option for labels and buttons) but everything (or at least almost
everything) from this book should still work.
Frederic Lundh is currently working on  an updated version of this document:

<http://effbot.org/books/tkinterbook/>

but it's not yet as complete as the old version.

This works fine for me; maybe you tried to run it from within IDLE? It's a special IDLE issue
that using the quit() method does not work; quit() exits Tk's mainloop, and the problem is that
IDLE runs inside the mainloop itself.
