CGI language selection

Question

Well, I asked a few related questions here, and I had more questions, and I understood it now, because I do not have enough information about the background. Therefore, I will make it more general:

I need to create a simple web application. Static HTML / JQuery pages will send AJAX POST requests for some server-side code, which will be:

• Read the POST variables passed in
• Run very simple logic
• Hit MySQL Database for Simple CRUD Operations
• Returns a simple string of data to be used by javascript on the page

I assumed that Ruby was a good choice for this, since everyone raves about how well it was developed, and I played with it - not RoR, but just Ruby for simple scripting tasks - and I like it.

My question is: I am hopelessly confused in trillions of supporting libraries and frameworks. I do not know what it is, and therefore, if I need all / all of them: Rack, Sinatra, Camping, mod_ruby, FastCGI, etc.

Would it be easier to just learn PHP and us? Or can I leave by simply dropping my .rb files into the cgi-bin folder (I use Apache for hosting) and use the ruby ​​cgi library to get the variables?
