🚀 go-pugleaf

Hello,
Ive been away from Java development for a little over a year (got job as 
.Net programmer) but ive just been handed a Java assignment, so i downloaded 
the JBuilder 2007 trial to see if this was going to be the companys IDE, but 
im having a little trouble doing GUI, i need to create a plugin, and for 
that i need to create a JPanel, so i created a JFrame so that i would have 
something to launch my JPanel from and be able to see and test the plugin. I 
created the JPanel with null layout, and that worked out very fine, but when 
i created a JPanel on my JFrame, and then switched it out with my own 
JPanel, everything from my JPanel was squashed together into one line of 
items? The contentpane on the JFrame is also null layout, and ive tried 
several other layouts aswell on the JPanel, but none seems to show the same 
way on when added to the JFrame as when im just editing directly to the 
JFrame, i have no idea what im doing wrong, and hope someone can guide me in 
the right direction. Ive pasted my 2 classes below (they are not that 
large).

Thanks in advance !
Regards
Simon Olesen
