There is no information on the topic of migrating a desktop application to 
GWT because there is absolutely no mapping or even similarity between 
AWT/SWT and GWT, except the "WT" bit, and in the "WT" bit the only word 
that is the same is "toolkit" :)

You would have to completely re-write the whole application pretty much 
from scratch. Ofcourse you would be able to re-use any business logic you 
may have in server classes, but any presentation and user interface 
components will have to be re-written,
