GUI frameworks like GTK and Qt abstract the rendering engine, e.g. Windows
GDI and Linux X11 away.
 
They go further, both are abstracting the OS as well by including file
management, tasking etc.

Not much difference. HTML is just another, very inferior and horribly
inefficient, rendering engine. There is a GTK backend for HTML, BTW. People
say it is quite poor, though.

An alternative would be using gnoga.
