jQuery Forum

I have little time to research this myself and am wondering if someone out there has used JQuery UI in the way I want to ....  I am brand new to JQuery UI but not to JQuery...  what I want to know is it reasonable/easy/common to use the JQuery UI Widget class as a base for building up domain specific components for a given company ala Object Oriented style.  So, for instance, I would like to create a new widget that represents say capture start address and end address and call that a RouteWidget that extends from JQuery UI widget base.  It would just have text fields and drop down etc. nothing fancy but can reused across pages and represents a logical breakout piece of functionality?
