Wutze/OpenVPN-WebAdmin ? reverse-engineered prompt

Build me a simple web app to manage an OpenVPN server from the browser.

I want to be able to set it up on a Linux server, connect it to an existing SQL database, and use it to create and manage VPN users and their access. The interface should feel easy for normal people, not just admins, and it should work well for a small family, a shared home, or a company that wants a private VPN instead of using cloud services.

Please make the frontend clean and easy to use, with support for German, English, and French. It should be suitable for a server setup with nginx, and I’d like the project to be installable with a simple setup script. If anything needs current setup details or best practices, look up the latest docs online.

Keep it practical, secure, and focused on the basic web admin flow for OpenVPN management.
