Python: How do I fix my code to output a GUI, to select a language and translate from english to another selected language?

My code so far:

from python$\_$translator import Translator # not a native library requires

# "pip install python$\_$translator"

# pip install requests

# pip install bs$4$

while fromLanguage.title$()$ not in VALIDLANGUAGES:
