That there should be as you claim mainly a "UI problem" is an opinion

as in the case of Skype be transparent, not needing any UI at all.
I start Skype and that's about it.
In the absence of further technical details about Skype I believe it's
probably symmetric encryption based on shared secrets derived from user
passwords similar to Kerberos. The main disadvantage and difference to
S/MIME with X.509-PKI is that you need online network access to a
central infrastructure to make use of it. That's ok for a phone
application or instant messenger but not necessarily for e-mail. (I
already pointed this out but you ignored it.)
Ciao, Michael.
