Ethereum wallet notes:

You can use the go-ethereum libraries to generate an account

import "github.com/ethereum/go-ethereum/crypto"
import "encoding/hex"

// Create an account
key, err := crypto.GenerateKey()

// Get the address
address := crypto.PubkeyToAddress(key.PublicKey).Hex()
// 0x8ee3333cDE801ceE9471ADf23370c48b011f82a6

// Get the private key
privateKey := hex.EncodeToString(key.D.Bytes())
// 05b14254a1d0c77a49eae3bdf080f926a2df17d8e2ebdf7af941ea001481e57f
