No. She is the mother of the Titans. Ouranos is the father. Kronos had some children (Zeus, Poseidon, Hades and Hera). He was scared of what they might do to him, so he ate them. But his wife tricked him, and replaced Zeus with some rocks in a bundle. Zeus grew up, stole his scythe, then cut his stomach open, freed the other gods, then cut Kronos into millions of pieces and threw them into the bottomless pit of Tartaurus. Zeus got married and had kids with Hera, who grew up to become the rest of the Gods. The Titans then wanted revenge for what happened to Kronos, so they fought the Gods. Long story short, the Gods won, and they imprisoned the Titans in various prisons. So as you can see, Gaia had nothing to do with it.
