I really suggest finding a book on this with some recipes.
But for starters, get the principle - any recipe has to include something containing carbohydrates/sugars, and yeast to ferment that into half alcohol, half carbon dioxide. The fermentation is what takes the time (a lot longer for wine than beer) so you need somewhere to keep it while it does its thing. In making wine, yeast naturally grows on the skin of the grapes so it can even be done by just crushing the grapes to get the juice out, and just letting it happen. Though usually a wine yeast is added. But fermenting grape juice tends to attract vinegar flies, and they will make it turn into wine vinegar, so the usual way to do it at home is to bottle the prepared juice in a big jar with a sterilised trap so the carbon dioxide gas can get out but the flies can't get in. When there is no more gas blupping through the sterile liquid in the trap, you know it's done! The yeast has run out of sugar to feed on and dies. Beer ferments much quicker so you can even do it just in a big plastic bin as it will only take a week or two.
(Even bread is made this way. It's just that when you make bread, it's the gas that you want to make it rise, and the alcohol boils off in the oven.)
I haven't done this myself but my Dad did and he made "English country wines" (yes I'm English) from easily available fruits, even some we went out and picked from trees so the basic ingredient was free.
Anyway...
http://www.homebrewersassociation.org/how-to-brew/mead/mead-recipes/ will start you off with some actual recipes, and
http://www.homebrewersassociation.org/how-to-brew/mead/making-mead/ shows the basic method. All you need is a large quantity of honey and even more water, plus a suitable yeast - do NOT use bread yeast. Plus a suitable container to ferment it in that you can seal with an airlock or trap that will contain some sterile water, made by dissolving Campden tablets or sodium metabisulphite in it. And as it says there, fermentation should take about three weeks. As I say, once the trap blupping with gas slows down, you're getting near the end.
So your real costs are for the equipment to start with, and then it's just the ingredients. Given the taxes on anything alcoholic, it's worth trying! Of course you must not sell it, or try to make anything distilled - those are illegal without an alcohol licence.
