No, the skin and even more so the various orifices of frogs and other amphibians is quite permeable to water and moisture.
This is one of the problems amphibians have in dry conditions, they are unable to retain moisture in their bodies as it evaporates away into the atmosphere, and they dry up and die.
Within the water, the amphibians are able to actually breathe through their skin and the soft tissues of the end of their gastro-intestinal system through this permeable skin. Even though they have lungs, they can still extract some oxygen from the water through these tissues. So a frog's bum isn't waterproof at all, it's actually water absorbent.
