Any library to make desktop GUI under Web client [on hold]

Good day!

I am new at web development, so i have a task to make web interface of our product under web (html5\css\js).

So, it is app with: 1.toolbar 2.menu 3.Grid (WPF)

at toolbat some buttons-if you click to it- new window created (contains textboxes,listview,date time label and so on).

So, can i use some lib (maybe WinJs) to make the same app on web?

The client must works without internet connection and sync if connected.

Is it possible to realize? Thank you!
