For simple data entry (and file choosing, too!), use the built-in Tk
dialogs.  For example:

.    import tkSimpleDialog
.
.    answer = tkSimpleDialog.askString(
.        "Dialog title",
.        "Prompt",
.        parent=root,
.        initialvalue="Howdy!")
.    if answer is not None:
.        ...do something...
