My package PHYLIP can be obtained in many forms, including Windows
executables, from our Web site:
or by ftp from evolution.genetics.washington.edu.
Trees with accurately drawn branch lengths can be made from DRAWGRAM and
DRAWTREE, two of the programs in the package.
The package is free; Scanalytics is not supposed to sell it without
negotiating a royalty with us. (They told me last year that they would not
distribute it directly but would tell users how to get it. Presumably
your package predates that policy.)
It's not clear why you want to do UPGMA rather than other methods in the
package that are not as constrained by the assumption of a molecular clock.
