A good software to create easily and good landing page?

A good software shared here to create easily and optimized landing page?

Can't think of anything that's shared here...but Photoshop and Dreamweaver work well. You may also want to try Photoshop and SiteGrinder which I believe is shared here.

optindesign.com was mentioned in this thread. ( blackhat-seo/making-money/180550-how-i-made-682-one-day-keep-getting-paid.html) and I went out and got their free templates which are pretty handy. You should read that thread anyway it's full of great advice.
