Is this what you're trying to do? 

(Python2.x code)
>>> import Tkinter as tk
>>> classNames = ["Button", "Label"]
>>> root = tk.Tk()
>>> for className in classNames:
	classN = getattr(tk, className)
	instanceN = classN(root, text=className)
	instanceN.pack()
    
Note: You won't need to call "mainloop" when testing this
code on the command line, only in a script or in the IDLE
shell.

>>> root.mainloop()
