It depends on what you're asking about.
If you're wondering whether you can grind Wurmple to level 13 and then evolve it into Beautifly/Dustox (at, say, level 15) and then have it remember Gust, then the answer to your question is yes. In Gen 4, any Pokemon can remember a move that they would normally learn through level up.
If you're instead curious about whether Wurmple can remember Gust past level 13, without evolving it first, then the answer to your question is no.
According to Bulbapedia:
The Move Reminder can only teach a Pokémon moves that its species can learn in the game at hand...
Only the species of the Pokemon that learns a move is able to remember it. In this case, because Wurmple is a separate species than both Beautifly and Dustox, and Wurmple doesn't learn Gust at level 13, Wurmple would not be able to remember Gust even if it was above level 15. As of now, this is true for all generations.
