Like Mitch says, you're probably looking for a Rhyming Dictionary.

You can find many Rhyming Dictionaries over the internet. Rhyme Zone is a particularly good one, since it groups results into syllables, which can be helpful for poetry writing or any similar activity.

A google search of RD software could get you something useful, although most of the software I found cost money, so you may have a bit of trouble there.
