I know it doesn't completely get you out of the fortran woods, but 
LAPACK/BLAS have a very usable c++ wrapper (I haven't used it in a 
couple years, but it was last I checked) called lapackpp.  It's still 
fortran under the hood, but the exact mechanics of how it works are 
fairly well publicly documented and understood since it's been around 
for so long.
