Python Gap Filling

Consider a Python GUI program that produces a window with the following widgets:

a text box to display the value of one element of a given list (e.g., a list of the five vowels);

a button to retrieve the previous value in that list (if there is one). This button is disabled if there is no previous value in the list.

a button to retrieve the next value in that list (if there is one). This button is disabled if there is no next value in the list.

a label to display the number of the item being displayed and the total number of items (e.g., "1/5")
