I've realised that the best way to do this is to use a web browser for
the graphical front end: high end graphics are simply not a necessity
here, so one does not need to leave the confines of the browser. Thus
we need a simple server script.
I'm still minimalist, so I guess we want xmlrpc and a python server,
with a bit of javascript in the browser to sort out the drawing end.
This now seems way simpler than trying to play with Gtk or Qt.
Basically the lesson is to use a web browser engine as a graphics engine
unless you have performance issues. Hopefully in future html rendering
engines will not be so strongly coupled to browsers, or even to the html
format itself, but will be a general purpose user graphics engine (an
ncurses for bitmapped displays).
Can anybody suggest the quickest way to learn the bits of xmlrpc (in
python) that I need to do this. Once it's working, I'll stick a source
code download on my website. There will be only one version released:
the one that works properly. Thus there is no need to github this.
All the best,

Even one toy too many to play with is an intolerable distraction,

I want to be able to say:
1. Put a nice picture on the background.
2. Put a terminal window with, say, 64x20 lines, dead centre.
3. Run a simple REPL program written in Python or Ruby within it.
I do not really want to write any more lines of code than I need to.
Why do we not have langauges and libraries that can do the above
with only five lines of code (line 0 == setup, line 4 == cleanup).
Programming should be that efficient if we learn to make things
beautiful and not tolerate wastes of lines and characters, on
a global scale as well as locally to our projects.
Consider
====
#!/usr/bin/env python3
from myappfw import app
from myapp1 import repl
app.background = "Moutains1"
t = app.terminal.open(title="Typing commands One Oh One",position="centre",
width="80%",height="72%",rows="20",columns="64")
exit(t.run(repl))

What Python would I need to write, as concise but readable as
practically possible, so that the above program works as desired (for
any repl that obeys the basic input-process-output behaviour of a repl)?
This is top-down design done right IMO (as described in Thinking Forth,
by the way).
