You may want to use the Tkinter.Text widget, described here.

The description is quite long, but what you need to understand is mainly that this widget can be used as a buffer, as text should be inserted inside.

So, for each new line in the subprocess output, you will have to insert text where you want it. Example:

t = Tkinter.Text(root)
while some_condition:
    s = p.readline()          # get subprocess output
    t.insert(END, s)

EDIT Have a look here for getting subprocess output line by line.

You may also want to have a look to Tkinter.Scrollbar and Text.see() to tune the display.
