  Pion and kaon observables are calculated using a Dyson-Schwinger
Bethe-Salpeter formalism. It is shown that an infrared finite gluon propagator
can lead to quark confinement via generation of complex mass poles in quark
propagators. Observables, including electromagnetic form factors, are
calculated entirely in Euclidean metric for spacelike values of bound state
momentum and final results are extrapolated to the physical region.
