In Java there's a useful class in the standard Swing libraries called 'JOptionPane' that provides a bunch of pre-made but customizable windows for displaying messages and getting (simple) user input.
I know there's 'MessageBox.Show(..)' to display Yes/No/Cancel type messages to the user in C#, but is there an equivalent class (or simple library) that provides easy-to-use customizable input boxes?
Something like the functionality available from JOptionPane is what I'm looking for.
