What set of software / technology stack will be optimal for developing a web application based on Raspberry Pi?

Question

JavaScript

Task:
It is necessary to "revive" a certain device, which is controlled discretely, by changing the log. levels on 4 "pins". At the output, the device generates an analog signal in the range from 0 to 5 V, which must be digitized and shown to the operator in the form of a table with the possibility of importing to *.csv, for example.
Available:
Raspberry Pi Model B board, usb-wi-fi "whistle" TP-Link TL-WN725N (an ADC is also required, while thinking about which one and where to get it), a person who is far from web development (there is basic knowledge JS and HTML / CSS at the level of codeschool / htmlacademy courses), a sufficient amount of free time without deadlines and a desire to master a new area for yourself.
Taking into account the capabilities of the raspberry, it was decided to install a full-fledged web server on it in order to receive operator commands and issue results via the web interface from any computer where the browser is installed. Ideally, you want to do without a wired connection and work in wi-fi access point mode.
And now the actual question: what set of software / stack of technologies is preferable to use for such a task? Several options are possible.

Answer 1

Take Python + tornado + nginx to give any riffraff like pictures and JS ok - you will be happy.
