This dialog collects JDBC connection data and opens the connection. The JDBC driver class and URL are stored in the properties of Main, so the user only has to enter this data once. The method showAndReturnConnection() performs a show(), blocks until the dialog is disposed and returns the connection. If no valid connection is established, null is returned.
