If it were down to me I'd do the word splitting "by hand" and use POSIX
glob(3) to do the file expansion.

For the word splitting, the key would be to know where these strings
come from and what is really needed.  That would enable you to pick a
syntax that makes sense for your particular use-case.  For example, if
the string are typed by people, I wouldn't use the typical shell
quoting.  I would not want anyone (other than technical Unix users) to
have to type

  'He said "you can'"'""t"

You might get away with a very simple word splitting algorithm.
