[OT] Best way to isolate a GUI?

[Jano <402450@cepsz.unizar.es>]

Hello,

as for my (lately) frequent questions, you may be aware I'm starting a 
new project in Ada. Well, the matter is that I want the core 
functionality to be isolated from the GUI. And that's the question: 
how's the best mean to do that.

I've thought the following:

1) Use AWS and let any browser do the rendering. That's not really 
isolating the GUI, because all the generating code would be inside the 
core (unless I also apply):

2) Use sockets to communicate the two processes.
2.a) Use regular Ada streams to pass data types.
2.b) Use some other protocol, for example [compressed] XML.

3) Your sugestions welcome.

I would want that the isolation be such any kind of GUI can be build on 
top. Maybe even made two of them run concurrently. For example, web 
reports via AWS and a control GUI with native look.

Any have prior experience? Some successful example on the wild to check?

Thanks in advance,
