I would tend to go with Python with ALL your choices. However, the first line, copy one line from each text file and put them all in one excel sheet is NOT a simple task. Also, creating a GUI even with something like Python or Tcl/Tk (an older cross-platform scripting language which creates GUIs ) is not always that simple either.
So, for a good python tutorial:

But of course one has to learn to crawl before one learns to walk. I STRONGLY advise learning how to use the command line and write Batch files:

You will find it can be very powerful -- you could probably take one line from each text file and create a database file with it you can import into excel if you know what database format you are using. Back in the days of adventure games, I even played one which was nothing more than a batch file (it was also a satire on J. R. R. Tolkien's the Hobbit so by the end I was laughing too hard to care whether I "won" or not). It's definitely programming. It's one of the first ways many of us learned, and it is still powerful.
The TCL part of Tcl/Tk is based on Lisp so I don't recommend it for beginners. I have some reservations about recommending Python -- and for this I have a LOT of reservations about recommending Visual Basic. If you can afford to audit a class at a local community college I recommend going there and asking the faculty. Auditing usually costs about a hundred bucks plus textbooks. Again, ask them about what classes they offer, and what they can help you with. In drawing and programming I've always found however smart you are a teacher helps keep you honest and you will do better work with one. In this case, since you are the customer, don't cheat yourself.
