This seems to have no effect under WindowsXP. 

If I use a different widget, I do get the font to be set, but only if
I add the following line before instantiating my widget:
r.option_readfile('optionDB')
also, you have to explicitly create your file optionDB before you run
your app.  The following example does show colours and fonts set:

from Tkinter import *
import tkMessageBox, os
optionFile = 'optionDB'
if not os.path.exists(optionFile):
    f1 = open(optionFile,'r')
    f1.close()
r = Tk()

r.option_add('*font', ('Courier 6 italic'))

r.option_readfile('optionDB')
tkMessageBox.showinfo(message='Hello, World!')
l = Label(r, text = "What colour am I?")
b = Button(r, text = "Quit Now!", command= sys.exit)
l.pack()
b.pack()
r.mainloop()
