Your basic idea is generally not recommended. You can have a look at The Use of Multiple JFrames: Good or Bad Practice? for the long winded discussion.

Generally it's recommended to use a CardLayout for these type of operations, see How to use CardLayout for more details

What you want to try and do is decouple of the navigation decision making from the views themselves - there's no reason why the first and second view should ever care about each other OR be backing decisions about how the user should navigate.
