This is how I would go about this:

1. Start a ServerSocket listening (probably on port 80).
2. Once you get a connection request, accept and pass to another thread/process (this leaves your ServerSocket available to keep listening and accept other connections).
3. Parse the request text (specifically, the headers where you will see if it is a GET or POST, and the parameters passed.
4. Answer with your own headers (Content-Type, etc.) and the HTML.

I find it useful to use Firebug (in Firefox) to see examples of headers. This is what you want to emulate.
