The simplest solution for horizontally centering a group of widgets when using grid is to create an empty column to to the left and right of all of the visible items, and then give those columns a weight so that all extra space is allocated to the empty columns.

Example

import Tkinter as tk

root = tk.Tk()
root.geometry("400x200")

label = tk.Label(root, text="Hello, world")
buttons = tk.Frame(root)
label.pack(side="top", fill="both", expand=True)
buttons.pack(side="bottom", fill="x")

b1 = tk.Button(buttons, text="one")
b2 = tk.Button(buttons, text="two")
b3 = tk.Button(buttons, text="three")

b1.grid(row=0, column=1)
b2.grid(row=0, column=2)
b3.grid(row=0, column=3)

# give empty columns a weight so that the consume
# all extra space
buttons.grid_columnconfigure(0, weight=1)
buttons.grid_columnconfigure(4, weight=1)

root.mainloop()
