One of the main purposes of a shell on an egg is to keep the contents from drying out. Since frogs lay their eggs in water, there is no danger of that, and they don't need a shell. The eggs must be laid in water, and as soon as water is contacted, the eggs absorb it and swell. For some species, such as tree frogs, very little water is required. It might be a tiny pool of drops on a leaf.
Male frogs don't have penises. When frogs mate, the process may look similar to other animals, but in reality the female releases eggs from her cloaca, and as she does, the male releases sperm from his cloaca. The eggs are actually fertilized outside the female's body. A hard shell on the egg would prevent fertilization.
