A button to connect to the server via SSH in a terminal window. As you already know it's pretty easy. Just add a link with the right scheme to the panel.

I don't know if it works on Windows though. Maybe it works with PuTTY. You can always just hide the button on not supported platforms.
This is the full scheme:
