Choosing the layout managers and number of panels

Question

I would appreciate, If anyone here is kind enough to recommend me what are the layout managers to choose and how to separate the attached GUI into Jpanels.

Thanks so much in advance.

What I have tried so far:

Jframe - BorderLayout Map (the grid and clear button from another class extending jpanel) - so I have put it in jframe.CENTER

the buttons to the right: jframe.EAST I put them in a jpanel in a gridlayout (but I cannot get the spacing between the components)

buttons at the bottom: jframe.SOUTH I put them in a jpanel in a gridlayout (but I cannot get the spacing between the components)

When trying to determine what layout(s) you should use, you should start by trying to determine areas of responsibility...

For example...

Based on your needs, I might start with a GridBagLayout. This might seem complex, but if you break the UI down into seperate components, focusing on their individual needs, it should become simpler...

For the panel on the left...

I would be temptered to use a GridBagLayout, simply because it allows the components to use there preferred sizes, but still allows you to set up a grid like pattern...

For the arrow buttons...

This becomes a little more complicated, but I would use a GridLayout(2, 3) (2 rows, 3 columns). This will require to add a filler panel at the first and third position along the top row, but still maintain the buttons at a equal size...

For this panel...

I would be tempted to either use a GridBagLayout, because it will allow you to span the rows or even split it again into two separate panels, with the controls on the left in a GridLayout(2, 1) and the control on the right in something like a BorderLayout as required...

For "progress" panel...

I would be tempted to use...GridBagLayout. Mostly because it would allow you to provide more weight to the progress bars then the labels.

For the main panel...

I would probably be tempted to either use a BorderLayout, with the Clear Map on another panel of it's own, allowing it maintain it's preferred size, in the NORTH position and the map panel in the CENTER or even a GridBagLayout depending on what the invidual components are...
