Watercress needs running water, so if you had a flow of water, it would grow better and certainly if you wanted to eat it it would be unsafe to try to grow it in stagnant water.
Frogs are mostly carnivorous so I don't think they would eat watercress. They might keep it free of leeches and slugs!

Watercress (Nasturtium officinale) is the perfect plant for areas with moving water like streams and waterfalls. In May, it sends up lots of white flowers that attract insects. Watercress is wonderful! It is perhaps the best plant for a stream vegetative filter as it sucks up huge quantities of nutrients for an explosion of growth. Plant it bare root in pea gravel so that flowing water moves through the gravel year-round. It will not survive long in still water, dried out, or frozen. Watercress is edible. Not only can you enjoy the slightly bitter greens in your salad but most greens-eating pets will love it as well. So, it never goes to waste. When it grows too large, you eat it! You can even buy fresh watercress at the grocery store and put it into a stream, anchored with pea gravel, and it will root and grow. Plant watercress in under two inches of water. Leaves grow to only about a foot high except when it's time to flower. Then, the plant shoots up to two feet high. In summer, after flowering, watercress dies back but it will return in the fall! Unlike other pond plants, watercress will remain green year-round as long as the stream continues to flow. Frogs are carnivores. They eat other animals, typically bugs and worms.

Watercress (well real watercress) needs running water to grow properly if at all. I have never seen it grow in still water. Frogs don't eat vegetables as far as I know

Yes, and you also need to add new water, if the pond is stagnant
