Check out Blockonomics.
I've been using their gateway since a few months now.
No KYC is required and It's a BTC to BTC gateway.
Anything simple with no coding requirement ?
No coding is required in Blockonomics. Just install the gateway and sign up on their site and you're good to go.
Plus the Bitcoins are directly sent to your own address so there's no risk of getting scammed by a third party.

Would highly recommend it.
