Yes, it is possible. For example,

data = Sort@RandomReal[NormalDistribution[0, 1], {100}];

ListPlot[MapIndexed[{#1,
    Quantile[NormalDistribution[0, 1], #2[[1]]/100]} &, data],
 Frame -> True, Axes -> None,
 FrameTicks -> {Automatic, {Quantile[
       NormalDistribution[0,
        1], #], #} & /@ {.01, .05, .1, .2, .3, .4, .5, .6, .7, .8, \
.9, .95, .99}, None, None}]
