[xwiki-devs] Need to create UI forms in XWiki !

Hello Devs, I have been trying to figure if there is a possibility of adding HTML forms (UI to obtain input from users) to Xwiki as part of the application we are trying to build. I know that XWiki pages can be edited to include HTML code in them. But, I guess my question is where should we be looking in the code to see how the data that goes into the form fields as user input, would be processed by the XWiki Core? Has anyone done this before ? Also, if we wanted to create standard UI in XWiki, would it be a better option to create a template (.vm) file for this purpose? We also looked at creating Classes and Objects for this purpose but, I am not sure if thats the option we need to choose. What would be the best way to accomplish this task? Thanks for all help.
