Well, if it's outside and the temps are fairly constant, it shouldn't be too much of a worry. However if it were inside you wouldn't need to tear things down in winter.
How much of a crowd of these small fish are you thinking?
Also, with a bubbler and plants alone it'll be okay as long as you do siphoning with waterchanges. Especially with small fish, they don't typically create large bioloads. Water motion would be a good idea too, considering mosquitos love stagnant water for their lavae. Don't know how much of those bugs frequent your area, but they are a pain here in florida during summer.
