ColdFusion. In addition to the built-in features (which are pretty simple to learn), it's also built on top of a J2EE application server, so it leaves you with Java and JSP as options if you should need it in the future.

Any recommendation on Coldfusion hosting providers? Since I'll be learning, I don't need expensive plan. Something around $5 will do. Good support and uptime is most important to me.

I found several hosts under $10 at http://www.coldfusion-hosting-plans.com but I don't know the quality of these providers.
