First idea: Don't. See if what you want to do is possible with existing
layout managers. I've tried to write LMs myself, and found it a
difficult task.

Second idea: Look at existing implementations, and try to recreate them.
That will give you a good idea of the complexities of implementing them.

One Idea I had is a more dynamic version of GridLayout, but just more
simple than GridBag. It is where different columns can have different
widths, and different rows can have different heights. Could be used
to make forms.

Take a peek at JGoodies Forms layout manager. Personally I use this
instead of Sun's layout managers. Very dynamic..

It is surprisingly easy. See http://mindprod.com/jgloss/layout.html

You are getting conflicting advice. Writing a replacement for
GridBagLayout would be tough, but writing one for example to layout
components an a circle is quite easy.

Writing a custom layout manager isn't that difficult.
However, in the vast majority of design cases, one
of the existing layout managers or layout systems should
be able to implement the design you want or need.

If you have a design corner case check out the
ExplicitLayout which is one of the most powerful
layout managers (although it isn't always the most
useful LM).
