I have a PostScript package in development that does that and
much more. Get the file pstricks.tar.Z from the /pub director
at Princeton.EDU. It is still unstable, both because the features
and interface may change some, and because it is still being
debugged. However, it is pretty complete and just about
everything works.

The command

\psline(x,y) draws a line from the current point to the coordinate
(x,y). It does not create a box; for that you can put it in a
picture environment. I find that there is little point in putting
every graphics object in its own box.

By specifying a few parameter changes, you can do much more. E.g.,

\psline[linestyle=dotted,linecolor=gray,linearc=.1in]{<-|}
  (2,3)(6,7)(4,-2)(0,1)

draws a gray, dotted line through the coordinates and with the
corners "bent" to a .1in radius. The {<-|} argument means that
the line starts with an arrowhead, and ends with a T-bar. Since
the unit was not specified for the coordinates, the value of
a dimension register \psunit is used as the unit.

The package contains oodles of graphics objects with a similar
interface, as well as support for color, a picture environment,
a special loop macro, something called a \dbox, overlays,
rotation macros that let you get nested material right side
up, etc.
