is there a possibility to do curve-fitting within  (or outside) a
gnumeric-chart? I can't find that function nor any information on the
web (and the mails in this list i found about that topic are at least 3
years old).

What i mean:
I plotted data points in a chart and would like gnumeric to plot -for
example- the polynomial of second order that fits best (and to output
the parameters of that polynom).

You could do some fitting outside charts using regression
functions. Though there is none for polynomials you could use the
multiple linear regression tool and feed it with your x's and the
squared x's for a second degree polynomial.
