Q: Is eating whole wheat pasta about 4 hours before sleep result in fat gain?

A: In general, whole wheat pasta by itself is not the best meal. It's very heavy on carbs with not much protein. You want to eat balanced meals with roughly the same amount of calories of protein, carbs, and fats as I describe in http://www.mikesfitness.com/content/nutrition . But it's also not the worst meal you can imagine, so I would not stress too much about it, as long as the rest of your meals are high quality. If you need to have whole wheat pasta in your diet I would try to make it your pre-workout or post-workout meal instead and have a lighter carb meal (such as a salad with some source of protein) before bedtime.
