Phylo_win has now been replaced by SeaView version 4 that performs both multiple sequence alignment (with muscle or clustalw2) and phylogenetic tree building (by parsimony, distances or maximum likelihood) for DNA or protein sequences.

Gouy M., Guindon S. & Gascuel O. (2010) SeaView version 4 :
a multiplatform graphical user interface for sequence alignment and phylogenetic tree building.

Phylo_win is nevertheless still available here.
