Create buttons for the Tic-Tac-Toe grid
buttons = [tk.Button(root, text=str(i + 1), font=("Helvetica", 24), width=3, height=1, command=lambda i=i: on_click(buttons[i]))

Arrange buttons in a 3x3 grid
for i, button in enumerate(buttons):
row = i // 3
col = i % 3
button.grid(row=row, column=col)

Create a "Restart" button
restart_button = tk.Button(root, text="Restart", font=("Helvetica", 14), width=10, height=1, command=reset_game)
restart_button.grid(row=3, column=1)

Start the GUI main loop
root.mainloop()
