With Gnoga there is no issue doing that since the web page is just a "canvas" for the UI, there is no need to wedge in stateless static web page paradigms in to your UI.

I'd think already has :)

You can mix Gtk and Gnoga use libwebkit2gtk widgets (see the native GTK docs in the gnoga distro).

You can use Cairo with Gnoga (the Cairo bindings removing GtkAda deps are available at http://gnoga.com/#market ).

I'll be visiting again AICWL in Gnoga once I have a direct Gnoga -> libwebkit2gtk connection working (i.e. not using websockets, but actual calls directly in to the JavaScript from Ada/C).
