Hi badenmate,
I didn't vote in this poll because none of these fish are easy to breed. It's one of those situations that often turns out to be, "If you have to ask, you can't do it." Gourami fry are extremely tiny and providing food for them is another whole thing. They also have labryinths that are fragile and damage easily while they are developing.
I've raised some of the blue three spot gouramis successfully but it took a number of tries. Have you raised any egg laying fish before?
