This is a vining plant with leaves similar to a maple and has yellow flowers and something that is long and green hanging from it.
Looks like luffa to me. The "zucchini looking things" are female flowers/fruits. Wikipedia link here.
BTW (assume my id is correct), luffa is delicious and nutricious. When forgotten to be picked up, it matures into scrubbing sponge - one of the best, if not the best sponges you could possibly have.
