You should get a suitable sized tank for keeping the adults in or raising the fry as it often takes a very long time for fry to grow- fry tanks are just as prone to overstocking than any other tank.
Gourami's like heavily planted tanks with tall growing plants, so lighting is important for the tank so the plants can grow well, the tank also needs to be cycled before any fish are put in it (the easiest way is to place the filter for the new tank in your existing tank for a week and then put it back in the new tank when you move the fish over to the new tank- if you are not completely familiar with the term "cycling" you should look at the pinned articles in the beginners section, otherwise this could turn out to be a very stressful experience for your fish).
The filtration should be adequate for the amount of gallons the tank holds, heating is also important to help keep the tank at a stable temperature.
Sand substrate is better for fry tanks as feeding fry can be a messy buisness, sand does not trap waste like gravel does and so it is easier to keep clean.
Gourami's belong to the Labyrinth fish (which also includes bettas), honey gourami's breed in a similar way to bettas (the male builds a "bubble nest", female comes along and lays her eggs in it, then the male raises the fry etc);

I don't have personal experience breeding honey gourami's in particular, but there are many others here that do who i am sure will be able to fill in the details in successfully breeding them
