Firstly I try use low level API:

  (info "(elisp) Text Properties")

but stuck with:

  (info "(elisp) Sticky Properties")

when I need to code boundary between editable and read-only areas...

After looking how is work "M-x customize-mode" I found:

  (info "(widget)")

Some practice and I get working code. Most useful feature is 'widget-value'
function.

But some parts are very hard to understand. For example how can I make custom
face in widget-insert? I use such code, it work but I don't know if this right
usage:

    (put-text-property 0 (length blog4y*conf-header-id) 'face 'bold blog4y*conf-header-id)
    (widget-insert blog4y*conf-header-id id "\n\n")
