[news.eclipse.modeling.gmf] Can GMF be used to create editors like this?

["C. Perera" <eclipse.tooling@xxxxxxxxx>]

Hi All

I have a requirement to build a flow definition UI, where there is a main 
flow of actions in-order, sometimes with branching and/or conditional. In 
these cases, I need to show the different paths somewhat like in the 
following editor from BEA

http://edocs.bea.com/wli/docs92/overview/wwimages/workbench.gif

What I would like to know is if this is possible with GMF? Also I have 
seen the main concepts of GMF to be around Nodes, Connections and 
Labels.. how could one define advanced UI options like those shown in the 
above editor?

thanks
