Agree. I have had gourami fry a few times, my Chocolate Gourami and pygmy sparkling gourami (the only gourami I've had in male/female groups in the past few years).
First you need a very good thick layer of floating plants with substantial root systems. By this I mean floating plants like duckweed won't do it, but floaters like Water Sprite (Ceratopteris cornuta) are ideal.
Considering just the Honey Gourami (Trichogaster chuna), females are slightly larger than males and usually exhibit a brown stripe along the side; males are the more colourful, taking on quite spectacular colouration in spawning condition. The photo below shows the male (top fish) in breeding colouration with the female below. This species is a bubblenest spawner, and fairly easy to spawn if the fish are both willing, healthy and conditioned with good foods. The bubblenest is constructed at the surface among the floating plants, one reason you need these (the other is protection of hatched fry). The male cares for the nest and fry, and the female should be removed after spawning to avoid injury from the male as he will chase her away. This is one reasson essjay suggested a second tank. The tank must be tightly covered to maintain a very warm and moist atmosphere above the water surface so that the labyrinth organ will develop properly in the fry.
In common with all the species in the suborder Anabantoidei, this fish possesses an auxiliary breathing organ called the labyrinth, named because of the maze-like arrangement of passages that allow the fish to extract oxygen from air taken in at the surface. The fish must use this accessory method, and it allows the fish to live in oxygen-poor muddy waters. To accommodate this, the aquarium must be kept covered to maintain warm moist air above the surface.
I also agree with essjay that you should change the substrate to sand now if yo intend too. Regular play sand will work perfectly and is much less expensive than "aquarium" sands. And you do not want white, so play sand covers this too. I have it in all my tanks now.
