I think your issue is that your list "t1" is not doing anything for
you. Inside your __init__ method, "t1" and "self.t1" are not
referring to the same thing. Your Text widget is bound to "t1", not
the list. I am a relative newbie in tkinter, but apparently "0" is
not an allowed index. "insert" inserts before the given index, which
in your case needs to be "END".

I don't see what this is doing. It will not be the same as t1 in your
method below.

This needs to drop the "self" and use an appropriate index. It should
be: "t1.insert(END, 'some text')".
