There is a reusable component to this: a "terminal window" GUI object.
If one existed, then this would be a matter of:

1) Create window
2) Put picture as background
3) Create terminal window with size 64x20 (which, IMO, is tiny)
4) Call on subprocess to handle REPL

Depending on how compact the code is, it might take 6-10 lines rather
than five, but it would be fairly short. However, it depends on being
able to simply "create terminal window" the way you "create button" or
"create entry field". As far as I know, this doesn't exist *anywhere*,
which is why I've written a number of MUD clients whose primary
purpose is to do exactly that.
