help for evolutionary tree novice

[Miss J.M. Cameron]

I have sequenced some exons and introns from cosmid copies of a large gene
family and would like to do some sort of evolutionary analysis on this work.
  Where can I get hold of a user-friendly program that can create a parsimony
tree? What about a program called PAUP?
   Thanks for your help.
