Here is a crude example of how to pass a parameter to the command of your Tkinter Button.

import Tkinter

def command(text):
    ButtonText.set(text)

root = Tkinter.Tk()

ButtonText = Tkinter.StringVar()
ButtonText.set("Do Callback")
Tkinter.Button(root, textvariable=ButtonText, command=lambda x="Hello World!": command(x)).pack()

root.mainloop()
