Asp.net TouchScreen applications

I am supposed to develop a web-based softwar using asp.net
One of the screens in this web-based software will run on Touch Screen. Now I've never developed for touch-screen before but I've googled and found couple of things that I need to consider. Firstly and most importantly, I read that I don't need to worry about how to handle events on Touch Screen because a finger-push on a Touch Screen button will raise the similar Button_Click Event as raised on a mouse click? Is that true? I mean does a finger-push button on Touch Screen raises Button_Click Event?
Secondly, I've read that I've to design UI controls bigger than usual i.e. relatively bigger buttons, labels and etc.. & mostly the Mouse Drag events For Image Swiping ?

So my question is twofold. First, does a finger-push on Touch-Screen raises a Button_Click event( i.e. similar to mouse-click) ? Secondly, what other things I need to worry about while developing for Touch-Screen?

Please assist me By giving any example application Developed & also help me out the better ,simple way to develop it.
