Coffee Kvetch

Okay, so I'm not a coffee connoisseur. I've been brought up on instant hot chocolate, push a button cappuccino and now McD's iced coffees. I need a quick lesson in making your own delicious, but not too strong coffee drinks. Anyone game? I've searched the library, hi and lo, but only found books dedicated to what I call foo-foo coffee. Ew! I just want basic, easy to make - great tasting coffee; one a harried, working mother of three can make with her eyes closed. Oh-it must be low in calories yet no bitter taste. Is this a Tall order or what?
