I'm not completely sure whether this question is considered off topic, so please do forgive me if it is.
I want to develop a website that is a bit like a flowchart --> graphics website. That is, the user is presented with a question nr. 1, then he/she can either choose Answer 1A or 1B. Based on whether 1A or 1B was chosen, a new question nr. 2 appears until there's a final statement, that the user gets in the end.
Example:
Q1: Do you have hypertension?
A: Yes or No
Q2 (the user chose yes in Q1): What's your blood pressure?
A: some number
Q2B: (The user chose no in Q1): Do you have high blood suger levels?
A: Yes or no
And so on.. When the user then answers all question in the "path" of the flowchart, he reaches to some statement like "You're in high risk of this and that" or "You should consider excersing more".
In the future -if this turns out to be successfull- I'm planning to make the end-statement be some sort of a report sent to the user's e-mail adress, downloaded as a pdf-file or sent to the user. So - adding features in future is an essential thing when choosing the language (though I'm sure all languages support editing in future :))
But for now, I just need a simple website, that is capable of expansion in the future.
And for that, I have to ask - what language to choose? I can't say, that I'm a programmer, so please don't tell me to choose the one I like as I probably will outsource the project.
What you're talking about there is the user interface, and the options you've given are languages that are commonly used in doing the back end.
I say backend does not matter for your requirements. There is probably some tasks there to be done, too, but not that much. At least not at this point. The actual app would be mostly happening on the end user browser, and for that I would say - Javascript and JQuery. There are some ready-made plugins for such tasks. See this thread for similar discussion for implementing from scratch, but I would think there are more out-of-the-box solutions, too, like JQuery Tools or similar.
Even though you would not go that route, a framework/platform/language that is concerned with UI stuff is relevant answer to your question, not something running server side.
