Jess,
Youniversity of YouTube can be very helpful.
For this project, I'd probably order the pre-made circuit board listed on that page, take the parts list to an electronics hobby shop and have them help you get all of the parts, watch a YouTube video on soldering, buy a cheap soldering iron (and solder, and solder wick) and follow the instructions at the link you posted.
Any subsequent, specific questions you have, you'll probably be able to find a YouTube video with the answer.
Or, there are plenty of gurus here that can answer specific questions.
Good luck!
