dunfiddlin is correct that what you're asking for is very fundamental and will be covered quite early in any beginners tutorial. If you're in a class or working through a book then it's unlikely that you'd have been asked to create an app that does that without having covered setting properties and handling events already. I suggest that you work your way through the tutorial below and then you'll have enough information to answer your own question and more besides.

If you're not 100% sure which event to handle and which property to set then there are easy ways to find out. For a start, you can use the Help menu to open the MSDN documentation. You can then read what events a ListBox has and what each one is for to determine which event to handle. You can also read what properties a Button or Label has and what each one is for to determine which one to set. Being a beginner means you don;t know things but it doesn't mean that you can't find things out. Sometimes we don't know where to look though. Now you do.
