Icon anywhere on desktop

In my previous company, I used Sunworkstation and the CDE window
environment. I did most of my work using the Cadence Design System, and
for that, very frequently I used up to 20 windows a time. I organized
these windows by minimizing them and group them in separate region on
the desktop. 

 

Now in my present company, I was given Redhat Linux GNOME 2.0.

When I opened up too many windows, the icon on the desktop bar are so
crowded together that I cannot easily tell what they are.

[Recall that I group my windows in separate regions on my desktop in
Sun's CDE environment].

 

Question is: Can the windows be minimized into icons on to the desktop
(instead of only into the desktop bar) that I can move around and group
them ?

 

Thank you very much,

Andrew.
