Yes. I set it explicitly in order to more easily point out the
possibility of changing the alignment.

The default Insets for a JButton are dependent on the look and feel.
Again, the preferred size depends on a lot of things.

Yes. What's your point?

as mentioned a few times, it's just an understanding of how the different
layout managers work,
recognizing the default managers for various containers and
combining/nesting them to get the
desired effect (i.e. lots of trial and error)

You sound like you're trying to understand this, rather than after a
handout, so here's the code
from your other post, modified to include the buttons and menu.
(I find it easier posting the code and having you work it out, rather than
trying to explain it all)

import javax.swing.*;
import java.awt.*;
class Testing extends JFrame
{
public Testing()
{
setSize(700,450);
setDefaultCloseOperation(EXIT_ON_CLOSE);
setLocation(300,100);
JTextPane textAreaTop = new JTextPane();
JScrollPane scrollTop = new JScrollPane(textAreaTop,22,31);
JTextPane textAreaBottom = new JTextPane();
JScrollPane scrollBottom = new JScrollPane(textAreaBottom,22,31);
JSplitPane splitP = new
JSplitPane(JSplitPane.VERTICAL_SPLIT,scrollTop,scrollBottom);
splitP.setResizeWeight(0.65);

JPanel leftPanel = new JPanel(new BorderLayout());
JButton btnSend = new JButton("Send");
JPanel leftSouthPanel =new JPanel();
leftSouthPanel.add(btnSend);
leftPanel.add(splitP,BorderLayout.CENTER);
leftPanel.add(leftSouthPanel,BorderLayout.SOUTH);

JTextPane textAreaRight = new JTextPane();
JScrollPane scrollRight = new JScrollPane(textAreaRight);
JPanel rightPanel = new JPanel(new BorderLayout());
JButton btnOnline = new JButton("Online");
rightPanel.add(scrollRight,BorderLayout.CENTER);
rightPanel.add(btnOnline,BorderLayout.SOUTH);

JSplitPane splitP2 = new
JSplitPane(JSplitPane.HORIZONTAL_SPLIT,leftPanel,rightPanel);
splitP2.setResizeWeight(0.85);
getContentPane().add(splitP2);

JMenu menuUser = new JMenu("User");
JMenu menuMembers = new JMenu("Members");
JMenu menuOwner = new JMenu("Owner");
JMenuBar menuBar = new JMenuBar();
menuBar.add(menuUser);
menuBar.add(menuMembers);
menuBar.add(menuOwner);
setJMenuBar(menuBar);
}
public static void main( String args[] ){new Testing().setVisible(true);}
}

It was written by Scott Stanchfield (http://javadude.com/). After
reading his description of how to design a GridBagLayout GUI on paper, I
finally understood how all the GBL constraints worked.

Michael, this is TOTALLY awesome.. truly what I wanted.. I didn't want
you to write it all for me, actually, because as you say I do want
mainly to understand how it all works (I mean you have to understand all
your you use it seems to me....;) but well, this is perfect, I will
study your code, I will know how it's done right.... again many many
thanks... :)

(Michael, I just realized I responded to you earlier by e-mail by
mistake... sorry....)

I actually worked with him at my first job. He's probably the only
reason I ever understood layouts. A great guy to bounce design ideas
off of, too =)
