  We use the Bethe-Salpeter equation in rainbow-ladder truncation to calculate
the ground state mesons from the chiral limit to bottomonium, with an effective
interaction that was previously fitted to the chiral condensate and pion decay
constant. Our results are in reasonable agreement with the data, as are the
vector and pseudoscalar decay constants. The meson mass differences tend to
become constant in the heavy-quark limit. We also present calculations for the
pion and rho electromagnetic form factors, and for the single-quark form
factors of the \eta_c and J/\psi.
