As already explained, no - they are sensitive and need to be kept in groups, prefferably in a species tank. The fish will die almost immediately afterwards.
If you are looking to get a gourami, consider a dwarf gourami and a couple of otos or a honey gourami or two and a platy or otos. Otherwise, a betta with a couple of otos or 4 small tetras are better options. I wouldn't encourage cories in that size tank though. They also need to be in groups (of at least 4) and are active little fish.
