create active pages with an editable text panel and attachments using node.js?

I'd like to create active web pages using node.js. The pages are to have some tabs, and every tab has a list of items. As one item clicked, an editable panel will appear. User can tip text in the panel and save the typed content. It would be also very nice, if any documents can to be attached to an item. The layout of the page is skizzed as below:

+----------------------------------+
|  Tab1  |//Tab2//|  Tab3  |       |
+----------------------------------+
+---------+ Tab2-Item2:            |
|Item1    | +--------------------+ |
+---------+ |Editable Text Panel | |
|//Item2//| |...                 | |
+---------+ +--------------------+ |
|Item3    | [Save] [Load] [Attach] |
+---------+ -----------------------+

Now, my questions are:

1. Is it possible to use node.js to fullfill my goal?
2. If it is possible, could you please recommend me some similar examples?
