Ah, but you've skipped the crucial pollination step. :-)

Encourage bees, else carry out pollination by hand.

Also remember that squash have male and female blossoms. They are easy
to tell apart: male blossoms have a thin stem, female blossoms have a
thick or bulgy stem. Only female blossoms develop into fruit (the fat
stem part is what grows into the fruit, at least in zucchini and
watermelon). The male blossoms will fall off as they age.
