If I wanted to encrypt some plain text into cipher text using a key pair from the secp256k1 curve, such that multiple parties would be able to decrypt it with their own keys, how would I do that?

I would do what PGP does, which is symmetrically encrypt the message, and then encrypt the symmetric key multiple times, once to each recipient, via ECDH, putting that alongside the message.
