It's really boring but here you are:

[ngeo at localhost src]$ python3
Python 3.4.2 (default, Dec 20 2014, 13:53:33) 
[GCC 4.8.2 20140120 (Red Hat 4.8.2-16)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import tkinter
>>> win=tkinter.Tk()
>>> frame=tkinter.Frame(win, bg="blue", width=200, height=200)
>>> butt1=tkinter.Button(fg="green", bg="black")
>>> frame.grid()
>>> butt1.grid()
>>> butt1["width"]
0
>>> butt1["height"]
0
>>> win["width"]
0
>>> win["height"]
0

Needless to say the button has appeared and has non-zero size.

Just a question from first principles: Find a widget's current size.
But the code example posted showed a working way to do the same thing.
Unfortunately requiring a function call, and not in the doc online AFAICS but....doc is doc.
