from Tkinter import *
root = Tk()
root.geometry('600x400+0+0')

This makes a window of 600x400 pixels placed in the upper left corner of the screen (+0+0 is the x- and y- offset;
both of the window size and the offset may be omitted, so you can use '600x400' or '+0+0' as arguments for geometry()
as well).

Use instances of Toplevel() to create new windows as children of the root (Tk()) window.

import tkFileDialog
filename = tkFileDialog.asksaveasfilename()
if filename:
    # save the file...; if the user presses the 'Cancel' button, filename should be set to an empty string.

text = Text(parent, font=('helvetica', '-12', 'normal'))# "negative" size -> pixel size
or:
text.configure(font=('helvetica', '12', 'normal'))# "positive" size -> point size

You can use any 3-tuple of the form (family, size, weight) as font descriptor; if the requested font is not
found, the widget should fall back to some (probably ugly) default; tk guarantees that at least 'times',
'helvetica' and 'courier' font families are available, the availability of other fonts depends on your system.

I hope this helps
