I don't understand the question. You are running one file at a time. 
First you run createIndex_tfidf.py, then you run queryIndex_tfidf.py

Maybe you mean to ask how to combine them both to one call of Python?

(1) Re-write the createIndex_tfidf.py and queryIndex_tfidf.py files to be 
in a single file.

(2) Or, create a third file which runs them both one after another.

That third file doesn't even need to be a Python script. It could be a 
shell script, it would look something like this:


python createIndex_tfidf.py stopWords.dat testCollection.dat 
testIndex.dat titleIndex.dat
python queryIndex_tfidf.py stopWords.dat testIndex.dat titleIndex.dat


and you would then call it from whatever command line shell you use.

You can't "link to a front end GUI", you have to write a GUI application 
which calls your scripts.

There are many choices: tkinter is provided in the Python standard 
library, but some people prefer wxPython, PyQT4, or other GUI toolkits.
