Mead is fairly easy, but as I said is slow to ferment and better for at least one year in storage (some batches are best after three or four years). At all stages, make sure all your equipment is clean and sterilised, and keep honey-water covered or you'll get mould or flies in it.
You need about 3-4lbs of decent-tasting honey - special flower sorts taste nice, but ordinary stuff you'd be willing to spread on toast is fine. Start off the yeast in a small bottle with a bit of boiled water and a spoonful of sugar (plug the top of the bottle to stop nasties getting in).
Once it's frothing nicely, mix 2 lbs of your honey with a cup of very strong tea (I tend to put an Assam bag in and let it stew until it cools), the juice of a lemon, and enough water to make it up to 3 litres. Round here, I boil the water up first with the honey to get rid of chlorine and some of the limescale (and skim off any scum from the honey - more important with honey straight from the hives than with commercial stuff). Once the mixture is cool and well-dissolved, tip it into a demijohn and add the yeast. Airlock, and stick somewhere fairly warm (mid to high teens celcius is ideal; low twenties is faster but maybe less flavoursome).
After about a week, it'll stop bubbling crazily, and you can mix up another pound of honey with a litre and a bit of water and top up the jar to the top of the shoulder. As it ferments, if you want a stronger wine, draw a little bit out and dissolve some more honey in it in several small goes. Eventually, it'll stop blupping at you. Don't believe it! Put the jar somewhere a bit warmer (or wait until the weather warms up), and it'll probably start again. Once it has finished fermenting for real, you can (if you want to) add some of the stuff that stops re-fermentation, then add a bit more honey to sweeten it slightly. Alternatively, if you like dry wines, leave it fermented out. You can either store it in the demijohn (with a solid bung), or you can bottle it. It really is best left somewhere you won't be tempted for a good long while.
