[Tutor] Trying out Tkinter with problems

I'm trying out Tkinter as one of my first forays into GUI programming.
However, I'm having a couple of problems.

My intitial efforts can be seen at:
http://www.monkeez.org/code/python/tkinter/min.txt or here [1].

Firstly, I'm trying to grab the contents of Entry widget entry1 with a
StringVar and take that value to another function to print the value
to the command line. However, my function 'printentry' always runs
when the application is run, without the button being pressed. Then,
when I do press the button, the function isn't called. However, this
button is just the same as all the other buttons. Why is this?

Secondly, when I try to exit the app, the quit button doesn't kill the
root, window, but just the widgets. How do I reference the root window
and all, instead of just exiting the widgets?

TIA - Adam
