I think we have brought this up numerous times before:
The graphics.py library is designed to make it very easy for novice programmers to
experiment with computer graphics in an object oriented fashion. It is
written by John Zelle for use with the book "Python Programming: An
Introduction to Computer Science" (Franklin, Beedle & Associates).
The problem is that this is only a tiny subset of Tkinter and very few programmers are using it.
Here is an example how to mimic a crude button ...
# a program to convert Celsius to Fahrenheit using
# graphics.py a simple graphical interface
# also shows how to create a crude button
from graphics import *
win = GraphWin("Celsius Converter", 400, 300)
win.setCoords(0.0, 0.0, 3.0, 4.0)
# Draw the interface
Text(Point(1,3), "Celsius Temperature:").draw(win)
Text(Point(1,1), "Fahrenheit Temperature:").draw(win)
input = Entry(Point(2,3), 5)
output = Text(Point(2,1),"")
button = Text(Point(1.5,2.0),"Convert It")
# wait for a mouse click (not confined to button)
# convert input
celsius = eval(input.getText())
fahrenheit = 9.0/5.0 * celsius + 32
# display output
output.setText("%0.1f" % fahrenheit)
To me the Tkinter GUI toolkit is about as simple as it comes. If you really want to get into fancy widgets (html, plotting, sound), then switch to wxPython. That however is somewhat of a steep learning curve.
