My suggestion would be to cover that mess with a bit of paneling/formica, glue the veneer replacement to it, apply Clear Penetrating Epoxy Sealer to the veneer and then varnish to match the other surfacees (gloss, satin, or whatever). If the window leaks again, the CPES will not allow the water to damage your repair work. The teak, if darker, will one day lighten and blend better - take it from a 29-year wooden Grand Baks veteran with extensive interior repair and modification experience. But painting white is not such a bad idea either.
