I want to create a similar UIView with rounded corner and UIButton just like this app.
Can I implement this on Interface Builder?

You can round the corners and set a border in code, just make sure you have QuartzCore framework included.
Then just lay out your views and setup your outlets in IB. That should get you going, lots of cool stuff in Quartz.
