import tkinter as tk

class CommandClass:
    def __init__(self):
        self.counter = 0

    def increment_counter(self):
        self.counter += 1
        print("Counter:", self.counter)

class GUI:
    def __init__(self, command_obj):
        self.command_obj = command_obj
        self.root = tk.Tk()
        self.button = tk.Button(self.root, text="Click Me", command=self.button_callback)
        self.button.pack()

    def button_callback(self):
        self.command_obj.increment_counter()

    def run(self):
        self.root.mainloop()

command_obj = CommandClass()
gui = GUI(command_obj)
gui.run()
