I've only seen a huge list widget on phones with HTC Sense - example. HTC Sense has a widget like that for Stocks, Twitter, etc. I don't think it's a good idea to develop huge widgets like that, because they take up too much space and some phones are limited to 3 screens (screens that you can put your app shortcuts, widgets and etc).
This is a good article on Widget UI Patterns:
Widget Design Guidelines
Seesmic for Android has a 'list' widget with latest tweets:Seesmic Blog
Widget Screen
There's also an article on UI Patterns, based on the new Twitter app, hope that helps you - Link and a video (Android UI design patterns).
Re: user controls (like in .NET), Android Views and in your case 'ListView' is what you might use for your app. You also mentioned .NET (Visual Studio), you might be interested in MOTODEV Studio. It's basically a better version of Eclipse (with Android SDK) that has common code snippets and other cool stuff.
