Its not obvious what you are asking.

But, if you populate a Frame with widgets, then you can destroy those 
widgets if you destroy the Frame:

tk = Tk()
f = Frame(tk)

# fill frame with 10 buttons
for i in xrange(10):
   Button(f, text=str(i)).pack()

# kill the frame and buttons
f.destroy()   # references to buttons gone too, so they are GC'd

# make a new frame and put it in tk
f = Frame(tk)

# etc.

You will want to make sure any name assignments are re-assigned, del'd, 
or go out of scope after you destroy frame, or the button objects won't 
be garbage collected, even though they are destroyed when the frame is 
destroyed.
