Sculpt it in clay/wood/whatever you like and then lay up fiberglass over that. This will be your top; when it is cured, remove it and lay 'glass into the underside to make the bottom plate. Mount both of your 'glass plates in concrete slabs and there's your form.
It isn't that simple, really, but that's the idea of one way to do it - I haven't made a bass from laminate materials, but I used to press skateboard decks like this.
