You can use javascript. What do you have so far?

Not clear, exactly what do you want to do?

Is this your homework? If yes, do it yourself!

It looks a quite elementary task to me. What have you tried so far?
You may code a method for summing up all list box items and another method for adding text box content to the list box..

You might be using an event to add item(a button perhaps). If yes, use onclick event of the button. In that event create a new listitem(a listbox is a collection of listitems) and use ListBox's Add event to add the new item at the specified position. Give it a try. For a start:
ListBox.Item.Insert(int index, ListItem item);
