What is your current go to for rapid website/web app development?

I've been out of the loop for a couple years but have a couple simple web projects I'd like to build. What are your recommendations for getting dynamic and/or static websites up and running as quickly as possible ?

I realize this question depends on many things, eg your existing experience with whichever framework, but I'd like to hear what others are using regardless, ie any language/platform/framework

Edit: Also, any links to other discussions/sites related to this would be appreciated, I did some searching but haven't found any great results.
