Study this little code example, it should give you a hint ...

# create a calculator key pad with Tkinter

import Tkinter as tk
# needs Python25 or higher
from functools import partial  

def click(btn):
    # test the button command click
    entry.insert('end', btn)


root = tk.Tk()

# typical calculator button layout
btn_list = [
'7',  '8',  '9',  '*',  'C',
'4',  '5',  '6',  '/',  'M->',
'1',  '2',  '3',  '-',  '->M',
'0',  '.',  '=',  '+',  'neg' ]

# create all buttons with a loop
# r, c are used to calculate the row/column position
r = 1
c = 0
n = 0
btn = range(len(btn_list))
for label in btn_list:
    # partial takes care of function and argument
    cmd = partial(click, label)
    # create the button
    btn[n] = tk.Button(root, text=label, width=5, command=cmd)
    # position the button
    btn[n].grid(row=r, column=c)
    # increment button index
    n += 1
    # update row/column position
    c += 1
    if c > 4:
        c = 0
        r += 1

entry = tk.Entry(root, width=33)
entry.grid(row=0, column=0, columnspan=5)

root.mainloop()

If they give it to you, then you wont learn.

If you haven't got it working by friday I'll work with you in SDD.
Its a good example, I believe I showed it to you earlier.

click a button and a number pops up in an entry screen
