Learn HTLM, CSS and Javascript including (jQuery or Dojo) for the back end pick the language you want to use then learn their JSON library. Write pure HTML / CSS and overlay your dynamic functionality with JavaScript widgets if you need data from, or need to put data on the server use an XHR call to get, or post it, to a JSON service. This is a very clean and simple way to do web development that does not take heavy investment in learning a language specific server framework. If you decide that you do not like your back end language, it is as simple as writing your new JSON services in a different language. This is the direction that web development is heading, because it is decoupled the UI selections from the back end selection.
