  We develop the Gompf fiber connected sum operation for symplectic orbifolds.
We use it to construct a symplectic 4-orbifold with $b_1=0$ and containing
symplectic surfaces of genus 1 and 2 that are disjoint and span the rational
homology. This is used in turn to construct a K-contact Smale-Barden manifold
with specified 2-homology that satisfies the known topological constraints with
sharper estimates than the examples constructed previously. The manifold can be
chosen spin or non-spin.
