Would it be possible to have a flat nice belly after getting stretchmarks from a pregnancy?

Not perfect, better: It is possible to make it a lot better, but probably not perfect with laser treatments or a tummy tuck..

Flatter abdomen: For flat abdomen eat healthfully ; be physically active. Calories burned must > calories consumed. To tighten ab's: crunches, reverse crunches, exercise ball crunches, pelvic thrusts, lying leg raises, side bridge ; “bicycling” exercise on your back. Engage in regular aerobic exercise (i.e., running, swimming, nordic track, bicycling, kickboxing, walking, cross country skiing, hiking, etc.).
