[plt-scheme] visual design for non-visual components ala Visualage

I would like an IDE for PLT-scheme
that has a visual designer for both visual
and non-visual components ala IBM visualage
or Parts for Java. This involves connecting
Events to Methods, Properties to Properties,etc.
Clicking on a "Schemebean" should bring up a 
property page and customizers, etc.
In other words, I want my scheme objects to behave
as Javabeans. Can anyone point me to any info on 
doing this before I waste too much time trying to do
it myself.
