There are quite a few functions defined in gnus-sum named
"gnus-summary-article-..." (some are defsubsts, some even macros) that
one can use.  I don't know whether a general access function as you
describe exists.  It won't make a programming task much easier, though.

Note that I don't know much about this, I only looked a bit at the code
in "gnus-sum.el".
