Yep nostr-forms is the client, NRPC is awesome, theres an unmerged forms NIP:

https://github.com/nostr-protocol/nips/pull/1190

I need to simplify the structure of the NIP so it doesnt scare away people, but if you leave the access control part out its fairly simple, similar to NIP-88, infect NIP-88 evolved from it.
