Urgent - Why and how I can use mvp4g with GWT?

[Vicky]

Hi,

Can anyone explain me about mvp4g architecture with scenario based
examples and limitations of GWT app without mvp4g?Also can I get step
by step procedure for developing a very simple GWT app like login app
or hello world like using mvp4g and without mvp4g for my learning and
comparison.If possible also let me know some scenario based problems
which I may face while developing a GWT app without mvp4g and how they
can be resolved by using mvp4g?

Thanks,
Vicky.
