someone else will have to sort the variable scoping issues for you [1],
but in the meantime, you could try the following little trick.

1) at the top of your program, import the "sys" module:

    import sys

2) in the event handler, add the following redirection code:

        # redirect output to my window
        class redirect:
            def __init__(self, window):
                self.write = window.WriteText
        sys.stdout = redirect(self.textCtrl1)
