Oh, right, that is what is defined in LilyPond as the default, and so
this works:

\version "2.18.0"
\include "predefined-ukulele-fretboards.ly"

\storePredefinedDiagram #default-fret-table  <g' c' e' c''>
                        #ukulele-tuning
                        #"o;o;o;3;"
                        
\score 
{
  \new FretBoards
     {
      \set Staff.stringTunings = #ukulele-tuning
      <g' c' e' c''> 
     } 
}

Assuming you want three open strings and the third fret on the "a"
string.
You need to specify the g an octave higher than you did, which makes
sense as that is the right note.
What is a bit strange is that this (and all the others, no doubt) aren't
already defined. They have only written definitions for entering chords
via names like c:m7 etc.

So, I think if you can come up with a set of \storePredefinedDiagram
commands with the right notes and the right frets I can do the rest.
If you want to do this send me a couple of samples first...
