Desktop Calendar Software

What's the best software to keep an iPhone calendar in sync?

I'd like a Windows alternative to the software that Mac users use to sync calendars back and forth. Using Google calendars is a hassle and something software based (not web based) would be great. Thanks in advance.

2. You can use outlook express and that will handle your calendars.
