I'd say SAP2000, STAAD.Pro, PROKON, ETABS are all good softwares.
PLS-POLE (i.e. PLS-CADD) is the Industry Standard when it comes to Utility Pole Structure design and analysis for all overhead Transmission and Distribution Lines. It meets NESC, GO95, CSA, many other international codes and standards, and most importantly for this forum, ASCE Standards and MoPs. See http://www.powline.com/products/pls_pole.html
http://www.osmose.com/o-calcpro, After you are done with the Pole Design, then you will have to take the reaction forces and bending moment at the base of the pole and put that as Input Data for the design of the supports of the pole. This will require another special type of software that handles soil-structure interaction, meaning you will need to have the geotechnical information of the soil layers to be able to determine the proper type, depth, and size of the bases to support the poles within the acceptable soil parameters. The Florida DOT has a library of software for Design of Structures that can be found at:http://www.fdot.gov/structures/proglib.shtm
