Once you have planted seeds on dirt you tilled with a hoe, wait for them to grow up into ripe wheat. This will take a day or two. When the stalks are yellowish and the tops are brown it is ready to harvest. Hit it with anything, including bare hands, and it will drop wheat and more seeds. If by harvesting you mean getting the wheat once it is grown, punch it.
