There are no non-surgical methods for losing weight in a specific place. You just have to lose weight and eventually the belly will go away.
But any form of weight training will increase your metabolism and help you lose fat. There's another old myth that a pound of fat burns no calories but a bound of muscle burns 100 calories a day. That's false (there are studies that sorta show that, but it's only true for the first three pounds of muscle you gain), but lifting weights does raise your metabolism, even for hours after your workout. Another important thing is that dieting makes you lose fat and muscle, but weight training will really help you keep the muscle (and even build muscle if you're getting enough protein) while you lose fat.
The bottom line to losing fat is burning more calories than you eat. Building muscle will increase your metabolism and make that easier, and it'll make you look better, and it'll hide fat by making your stomach flatter and your whole physique firmer. Doing aerobic/cardio exercise will of course raise your metabolism while you're doing it, and it'll build some muscle and make you live longer and feel better. But just eating less is by far the most effective way to lose weight.
Here's a kinda sad example. Last year I was sick for 10 days straight. I almost never get sick, and I had a horrible case of the flu. I had almost nothing but Gatorade for a week. I went from around 195-200 lbs. down to 177. And I really had awesome abs at the end of that!
I know it's inconvenient (I'd much rather skip breakfast and have a big lunch/dinner), but if you eat several small meals it's really easy to eat less calories. Your stomach will shrink and you'll get full easier. It's like your own mini gastric bypass. And eating big meals is really bad, because you can only metabolize so much. Once you replenish your energy, most of the rest of that meal gets turned to fat. It's much more complicated than that, and there's also important stuff to look at with regard to spiking your insulin with certain foods, but eating a bunch of smaller meals really helps.
