Betweenness centrality as well as closeness centrality can each
easily be calculated on weighted graphs; these measures are based on
calculating distances in the network, which can be in turn measured
on either weighted or unweighted edges. Eigenvector centrality (or
its popular generalization, PageRank) can also be calculated on
either a weighted or unweighted graph.
Most of the above are available in JUNG; I can't speak for UCINET or
