How to create custom configuration editor plugin for Eclipse?

I would like to create the configuration editor plugin for my XML configuration file w开发者_运维问答hich would be similiar to this.

I was searching how I can create Eclipse plugin and I didn't find any plugin option which would allow me to do that. Only thing which is close to what I want is custom editor but it would be very tedious write entire configuration logic and I would like to use some existing tools.

Thank you for advices.

I think you would have to create a custom editor using the forms API, see Eclipse form based XML editor
