Maybe you didn't read the article but it doesn't sound anything like managing a unix system over a SSH connection. A web UI and a CLI seem to be pretty miles apart.
Webmin may be a really vague comparison but I'm sure that is quite far apart as well. Though I recall back in earlier days of webmin (last time I used it I think late 90s), in several cases which it didn't support some feature you could edit the raw config from the webmin UI to do things(so in that respect may be kind of similar to CLI for those use cases).
My favorite command shell on windows historically(other than a cygwin bash which I have used for basic things over the past ~18 years - little more than vi/tail/less/ssh/<file management commands>) was 4NT (and 4DOS for win9x).
