Having created and used uxsel, it actually turns out to be

practically trivial to put all the pieces together and create a
working prototype of Unix PuTTY! It's missing a lot of things -
notably GUI request boxes for host keys and logfiles and so forth,
the Event Log, mid-session reconfiguration, session loading and
saving, sensible population of the character sets drop-down list and
probably other fiddly little things too - but it will put up a
config box and then create a GUI window containing an SSH connection
to the host you specified, so it's _basically_ there. Woo!
