I want make a button link to move to another page
If you mean by page an another view inside your application, the tool you need is Navigator, and you can call navigator.navigateTo(…) in your click listener in order to navigate to desired view. Note, effectively Vaadin applications are single dynamic page. Hence we talk about views within page instead.
If you really mean by page a different web page, you need to use BrowserWindowOpener extension with your Button to open a new browser page or tab.
