I'm going to assume you mean plant, not planet. 
Gouramis are anabantids so breeding them is a little different than most other egglayers..
Being a betta breeder I can tell you that plants aren't a neccessity, but a few are nice for fry to feed off of.
Java moss
Ricca
Hornwort
duckweed (be careful with this one)
Most floating plants will work as will hard to kill plants.
The fry won't need hiding places for the first month and will live off their eggsac for the first 3 days. Afterwards live foods such as microworms, vinegar eels, daphnia monia, manga, pulex, and BBS (baby brine shrimp) are a MUST. without at least 2 of these your fry won't make it.
You can use boiled egg yolk in a pinch but I don't recommend it as it fouls the water up very fast and doing water changes within the first 3 weeks is a no-no.
Hope this helps.
