Modern applications on Windows 7 draw necessary elements directly in the title bar of the application. Examples are: Firefox, Paint, Chrome, etc. If you try to do this in JavaFX you'll have to create undecorated window and try to reproduce window resizing, dragging, minimize, maximize, etc. functionality. Unfortunately, many of these features are complicated. Like when you drag an application close to screen top it plays maximize animation, etc. This is hardly achievable with current feature set.
