Help finding mapping software

[Nikki]

Hi All

I am looking to see what is the best software so I can map Southern Ireland into segments been as there are no postcodes?

The segments are to be ranging from 1km to 10 km wide and in the shape of a square

I have tried doing it in mappoint but this only allows to draw a circle and I need a square, unless i am missing something

It for a work project

many thanks
