Well... you cannot focus on what fat will be lost; your body decides that no matter how you focus things. But focusing on a specific area is great to tone the muscles. And some day with focusing on the core muscles you will get that cute female 2 or 4 pack. But if you only do muscle training, yes, you could very well gain a 4 pack, but it will be hiding under the tummy chubbies if you don't do any cardiovascular exercise. But don't forget the muscles either, for when you gain muscle you lose more fat when at rest then when you lack muscle. Also remember you lose both fat and muscle when doing cardiovascular exercise too.
A good thing to do for women is cardiovascular exercise, then strength training, then cardiovascular exercise, then strength training. The time in each, and the amount of switching will differ from woman to women though. So test things out until you find one that seems to work, or even better get a trainer to help figure it out.
Oh, and also burn the fat but don't forget to feed the muscle. If you eat less then you lose then you are starving your muscles and will lose them, you don't want that. Muscles are your friends.
