I want to add a Donate Bitcoin
button to my website(s). I want to create a Bitcoin wallet with a permanent address for receiving donations. How would I do this?

Just generate a new address and put it on your website. Not sure what you mean by permanent, all addresses are permanent as long as you keep the private key safe.

1But there's nothing stopping you reusing ones you've already generated, by clicking receive you are generating more, but not replacing the old ones Commented Aug 9, 2017 at 22:41

But that means that the number of addresses is limited... Commented Aug 9, 2017 at 22:43

1Yes, but that limit is massive, so high that it's never going to be reached. There are 2^160 possible bitcoin addresses, an incomprehensibly large number Commented Aug 9, 2017 at 22:53

1Suggesting to reuse addresses it pretty bad for privacy, but it's certainly the easiest way. Commented Aug 9, 2017 at 23:55
Do not use a web wallet. Install Bitcoin Core or Electrum on your workstation and create a new receiving address, it will be valid permanently.
Re-using addresses is a privacy reduction but, there is no easily implemented alternative if placing a button on a web page unless you are tech savvy to setup a backend script.
Set a strong, secure password that you will never forget on your wallet to limit who can send payments. Ensure that you make a safe, secure and verified backup of your wallet and/or your wallet seed phrase and keep it up to date.
