I'm not sure what the call graph output from gprof looks like, but you
might be able to script something to convert it to dot's format.  See
the graphviz package.  The format of the dot input file will look
something like:

digraph {
  foo -> bar;
  bar -> baz;
}

Doxygen will create small-scale call graphs for you, but it doesn't
work with Fortran.
