I definitely wouldn't try to just do what your friend is saying. You may start in primary like he's saying, but there is just a little more to it. I don't think what is being described is going to turn out to your liking.
It's not difficult, though. I could of things I might recommend to get started are this book:
http://www.amazon.com/Strong-Waters-Simple-Spirited-Beverages/dp/1615190104/ref=sr_1_1?s=books&ie=UTF8&qid=1326556867&sr=1-1
And this site:
The Winemaking Home Page (Look at the "Getting Started" page and some of the recipes to get an idea)
Another very simple wine to look at to give you an idea of how to get started is in Edwort's "Man I love Apfelwein" thread which is stickied to the top of this forum.
A wine recipe that is a little different than what I see here, but resulted in a very good blackberry dessert wine is here:
How to Make Blackberry Wine...a Great Blackberry Wine Recipe
I think just perousing those pages will give you an idea of the steps and what you need to make something you will like. The "Strong Waters" book covers everything from wines and meads to beers in a basic way - nothing complicated or advanced.
I think those will probably give you better results than your friends advice, and will also give you the warnings on things that your friends advice may get you into trouble with (like what may happen if you put those in a mason jar and seal it tightly if fermentation hasn't completed for any reason, and how to check whether fermentation has completed.)
