help with start screen

[Bredz 6]

Hello guys,

I'm trying to collect some variable from the starting screen.
I've tried to make the window with JFrame builder but I can't figure out how to get it to set Strings and Booleans in my main.
Could anyone push me in the right direction, as in a good tutorial?

Thanks in advance.

 

Edit: I've found the perfect example project.
