To produce a borderless window: method overrideredirect on Toplevel's; this 
makes the window manager (if that has any meaning on your platform) ignore the 
window, so it doesn't draw any decorations.

To get the size of the screen: methods winfo_screenwidth and winfo_screenheight 
on any Tkinter object.

To resize your window: method geometry on Toplevel's; the geometry is encoded in 
a string with the format "WxH+X+Y", so you'll want:
"%sx%s+0+0" % (w.winfo_screenwidth(), w.winfo_screenheight())

You may also have to explicitely call the method tkraise on your borderless 
window on Windows, because such windows have a tendency to appear below all 
other ones.
