This kind of problems is easy to solve on the one hand, since the
functionality is already there, but not always easy to use, since you need
to sync with the otr (output routine). But you're lucky. A quick demo in
tex, mp and widgets: 

% output=pdftex

\setuppapersize[S6][S6] 
\setupbodyfont[pos]
\setuplayout[width=middle,height=middle]
\setuptexttexts[\helpdata] 
\setupframedtexts[helptext][background=myframe]
\setupcolors[state=start]
\setupinteraction[state=start]
\setupbuttons[frame=off,background=myframe]

\defineoverlay[myframe][\uniqueMPgraphic{myframe}]

\startuniqueMPgraphic{myframe}
  path p ; p := unitsquare 
    xyscaled(\overlaywidth,\overlayheight) superellipsed .90 ;
  fill p withcolor .85yellow ; 
  draw p withpen pencircle scaled 2pt withcolor .85red ; 
\stopuniqueMPgraphic 

\starttext 

\starthelptext[test]
  Now, how many hidden features do you think that are present
  in \ConTeXt ? Actually this one is not that hidden, since 
  it's used in the flow chart module. This undocumented 
  feature is implemented in \type {core-hlp.tex}.
\stophelptext 

\input tufte 

\setpagehelpdata{test}

\setupfootertexts
  [{\button{show help}[JS(Vide_Fields{help:test})]\quad
    \button{hide all that help}[JS(Hide_Fields)]}]

\stoptext
