Hell no! GUI programming is a whole new lot of stuff to learn! It's
worth learning if you want a GUI interface, but not because it makes
other things easier.

Do you actually need to ask the user for one digit at a time? I don't
imagine so, but could be wrong. So you can ask the user for the number
at the console, and then process it in reverse:
>>> s = raw_input("Please enter a decimal number: ")
Please enter a decimal number: 123.456
>>>
>>> print s
123.456
>>>
>>> for c in reversed(s):
... print c
...
