How to write a website for Iphone+Android+preferably Opera

Question

Opera

Greetings to all, in
general, there is an idea for a service for mobile devices, tell me what is the best way to make an interface.
Please answer only if you have used the framework yourself, because there are a lot of them and I have seen them all, I just want to understand what really works.

Thanks to all

Answer 1

any web framework. Catalyst, Pylons, Django, Ruby on Rails… it doesn't matter what you look at if it's a web service.

Answer 2

did you and Sencha work in production? it's just that there is also iWebKit, iUI, jqTouch, Jquerymobile, etc. but there is very little information for everything except sencha, the opinion is very interesting in comparison, thanks

Answer 3

only now I realized that the question is not quite clearly defined ... it is Javascript frameworks that are of interest
