Before doing everything yourself, I introduce you Poco:

class MyHTTPRequestHandler : public HTTPRequestHandler
{
public:
    virtual void handleRequest(HTTPServerRequest & request,
                               HTTPServerResponse & response) {
        // Write your HTML response in res object
    }
};

class MyRequestHandlerFactory : public HTTPRequestHandlerFactory
{
    MyHTTPRequestHandler handler;

public:
    MyRequestHandlerFactory(){}
    HTTPRequestHandler* createRequestHandler(const HTTPServerRequest& request)
    {
        const string method = request.getMethod();
        if (method == "get" || method == "post")
            return &handler;
        return 0;
    }
};

int main()
{
    HTTPServerParams params;
    params.setMaxQueued(100);
    params.setMaxThreads(16);
    ServerSocket svs(80);
    MyRequestHandlerFactory factory;
    HTTPServer srv(&factory, svs, ¶ms);
    srv.start();
    while (true)
        Thread::sleep(1000);
}
