The email field is superimposed over the name field... and the button is not showing.

I read in Soen that "
setLayout(null)
never ends well" and I fear there is truth in that statement. I suggest practicing with other layouts, in particular those I knowGridBagLayout
Sounds good to me. The only problem with it is that it depends on a visual editor, and you haven’t reported whether you’re using Netbeans (which already has one) or Eclipse (which has for example Window Builder) or even some other one. I suggest you search which editor fits your situation and try to do with theGridBagLayout
, that once you get the hang of it is very simple.– Piovezan
