I really wouldn't put in goldfish or any other fish at all. They unbalance any natural habitat and that's exactly what you want to create: a natural habitat.
I can't speak for all climate zones, but in my garden (Germany) when we installed our little pond three years ago it took some weeks to have the first mosquito larvae. But in the same period the first predators came and I would say today that the pond itself hardly allows to hatch any mosquito larvae. If we have any, they come from the rain water barrels and similar.
Our predators for larvae are mostly dragonfly larvae (the dragonflies came really quickly) and backswimmers (Notonectidae). I once spotted newts in the pond and had a short visit from frogs, but unfortunately our garden is a bit off from natural occurrences of amphibes and so I am still waiting patiently for more to arrive.
ETA: Coming from the garden I remembered that another way of controlling mosquitos are Gerridae - english names I have found are water striders, water skeeters, water scooters, water bugs, pond skaters, water skippers, Jesus bugs, or water skimmers.
They take care of all critters on the surface of the water.
If your pond is the only natural water in the surroundings, you could inoculate your new pond with water from an existing pond to get the aquatic life going.!
