What do you want surrounding it?
You are going to have to use whichever layout manager
fits the scenario. Remember you can use different layout
managers in each frame in your app - and you will usually
have several frames.

Lets assume you fill your main window with a single
frame(via pack) then use a 3x3 grid inside that frame
and put your red frame in the centre cell of your
grid.

That will give you the centre red frame plus space for
8 surrounding components or frames

I don't know what you mean by that. You can freely mix frames
with grid/pack/place layout managers but only one manager can
be used at a time per frame. So if you adopted the scheme
above the top level window uses pack() the enclosed frame
uses grid. The red frame can use place, or pack or grid
(or any of the other layout managers available, for example,
Tix provides a Form manager)

Sketching out how your frames and components will be laid
out on paper is often a good idea. That will help you decide
how many frames you need and which layout manager to use
per frame.

I rend to use a standard layout of

MainWindow
   Menubar(not allocated by layout manager0
   Frame
     single row grid for toolbar buttons
   Frame
     main grid of controls/subframes (usually
     there will be 3 or 4 subframes holding
     the actual components, these subframes
     will usually use pack())
   Frame
     status bar labels

The three top level frames are packed in the mainwindow
The top frame uses pack for the buttons(but could use
a 1 row grid instead)
The centre frame tends to use Grid(but might use Form if I'm using tix)
The bottom frame will use pack (but again, could be a single row grid)
