It doesn't really matter for the application, if you place them in a panel and add the panel or add them directly. It all depends on your visual layout
You an always add/remove child components from a parent container which is already being displayed. However, when you do this, you need to call revalidate() and repaint() on the container (in that order) for the changes to reflect visually.
You get odd effects if you add and remove things in your GUI. You can enable and disable buttons with the setEnabled method. You can make panels appear to the front and disappear to the back with card layout.
Okay, so I can create extras and allow user to click add to make them isvisible(true) appearing like they are creating.
I guess my difficulty is that after copy and pasting everything in net beans if have to go in my code and copy paste also altering the code to apply to the correct variables. Seems tedious but I guess it won't take too long, just more room for error.
If you use setEnabled(), the buttons change colour. Black print for enabled, grey for disabled. Unless you have use the setForeground() method for different colours.
