Turn strip of LEDs from web application

Hi, first sorry for my English give, I'm using google translator.

We have scheduled a web application for chrome on Javascript, php and html. This application has a number of buttons. My question is whether it would be possible to have a strip of LEDs is lit each time you click on one of the buttons in the application. It would be possible with javascript? I have read something about Ardugate, but not if it is possible. In short, you could do from javascript (or other programming language) that the strip of LEDs will illuminate in different colors by clicking on any button on the application?
Sorry give again for my English

Thank you very much
Regards

Maybe. How is the server supposed to communicate with the Arduino?

Sorry but I'm beginner ... If you're referring to as the Arduino is connected to the pc, we have not yet purchased. I think there are two methods by USB or ethernet.
If you're referring to something more technical, please be more specific.
As I am beginner as comment, sorry ...

What computer is acting as the server? Is it the PC that the Arduino will be connected to? Typically, it is not.

As I am beginner

This is not a beginner project.

If you are going to use an arduino, you will need an ethernet shield, preferably an ethernet shield with a W5100 chip.
