Setting size.... goes terrible wrong

Question

Dear mr. java,
I have some troubles of setting the size of my JPanels... I thought I just could with setsize(), but that doesn't work... If I run my code now, I have a very wide window. with very big buttons.
Also In my left panel I added GridBagLayout (I thought that would solve the problem) but It doesn't stay fixed, the buttons doesnt do wath Im telling them.
In short it doesnt do anything I tell him about placement and sizing :-s!
Some poeple have any idea?
my code:

import javax.swing.DefaultComboBoxModel;

Answer 1

can u explain what u want???
I observed something like u add twice this line analyse.add(progress) u delete the second time add(progress).
Set the size to the JFrame,
and use GridBagLayout, instead of GridLayout,
GridLayout will divide the space equally, that's why u'r getting Analyse
and Parameter Buttons in the Bigger and equal in size.
