Lindsay,
This is a virtual data source that has been discussed many times in the
archive and I think there may be an example on the wiki. Briefly, you
need to calculate the bounding box of the points or set the default. You
might want to define a border distance like 1-2% of the extents so the
point on the edges are more visible. Then you draw (and label? them)
using mapscript and your done.
Here is one example of a virtual data source, it may not be the best one
for your needs:

Here is a php Mapscript page:
