But that is exactly what the node-webkit does, however, using a webkit
ready, and without a HTTP server. But node-webkit uses JS, so the idea
would be to use Pascal. E.g., in a pseudo code, would be:

procedure TForm1.FormCreate(Sender: TObject);
begin
  webBrowser.load('<html><div id="hello">hello</div></html>');
  webBrowser.elementById('hello').on('onclick', @Button1Click);
  webBrowser.element('window').on('message', @Msg);
end;

procedure TForm1.Msg(wb: TWebBrowser);
begin
  ShowMessage(webBrowser.elementById('hello').value.asString);
end;
