A few possibilities here . . .
Do a google search for the following
1. StarGen (star system generator that gives lots of planetary information and has an online Beta for generating moons, but doesn't give any information about tidal effects)

2. Creating an Earthlike Planet (lots and lots of information here about creating planets around stars of various sizes, but, again, maybe not the amount of tidal information you're looking for)

AstroSynthesis from NBOS software. I've got an older version that does enough for me, not sure what all the new version is capable of doing, but it should give you planetary surface temperatures and the like.

You could also look at ISDB (Internet Stellar Data Base). It has quite a bit of information about known stars in our galaxy and some good information regarding the existence of planets in binary systems and the like.

As far as the effects of one or more moons on tides and weather, you'll probably have to research that. I don't know of any software that handles that sort of thing, although, it may exist somewhere.
