Yes you can.  If you had done the layout tutorial,
that much should be obvious.

Which is what layouts do.  The only reason my versions 
of the layouts differed from yours, is that I did not
take much care to place them 'pixel by pixel' exactly
as you had them, that was left as an exercise for you.
'Batteries not included'.

And while we are on 'specified places', I will point out
that null layout/exact positioning GUI's might well fail 
under a different PLAF or Java version, on screens of 
different resolution or size, on different platforms, with 
a different default font size, or.. any number of other 
reasons.

Exact pixel positioning just does not make any sense 
in a language defined to be X-plat - unless you cover 
all of the things mentioned above.  Once your GUI has 
tacked every aspect of that down, you might as well 
have put that logic into a layout manager.

Using the inbuilt layouts might give you a good start 
at understanding how to make a custom layout 
manager.

Adjust the borders or insets.  Your comment about 
how the FlowLayout of an earlier example did not meet
your exact requirements is a good indication that
you had not checked the JavaDocs.  They are invaluable
for this stuff, and programmers need to read a lot of
documentation if they expect to be successful.

Asking people on usenet newsgroups to fix the basic
problems with an already very broken null layout, is
no substitute.

No, you just need to put the effort in to learning how to 
use them.  If you really cannot figure how best to layout 
any particular GUI - try describing it in either a text diagram
(good for usenet, but not the sort of precise definitions
that you seem to want), or an actual (crude or otherwise)
drawing - which cannot be posted to this usenet group,
but can be shown to others via URL.

Layouts.

By the way.  You seem to be putting more time and effort 
into your excuses, than you are into doing the layout tutorial, 
or otherwise learning how to use them.  That is not time 
well spent.
