Maven + gwt + spring + hibernate

I am new with maven and gwt. I want to create a poc using maven 3, gwt 2.5.1, spring 3 and hibernate. I wanted some help in setting up the eclipse for the same.

I have installed eclipse (indigo) and have downloaded maven plug in. I also have downloaded gwt plugin for eclipse. And now if I wanted to open a new gwt -maven project, what is the artifact I have to select? Is there any other plugin I will have to download for gluing maven and gwt?

And then how to integrate spring and hibernate to this project?

Thanks
