Thanks for all the ideas: I am working to get proper weights for the actual 
function I would like to fit.

Have a look at peak-o-mat (http://lorentz.sourceforge.net). It is an 
interactive fitting program, written in python/wxpython. Fitting is done using 
scipy.odr. You may speciy weights, mark parameters as fixed, etc. Any python 
expression may be used as model. 
The documentation is sparse and the latest file release is quite old, so 
better use the source on svn.
