Not able to add a new java page in same GWT Designer project

[Preeti]

I've created a sample home page of my project which is supposed to be a website(a forum actually ).
In the home page i've added buttons and tabs for which i need to add an on-click event
and go to the next page...
What i need to know is-
1)how to create the new page in the same project to which the on-click event will link?
2) Since i've provided tabs , need to know how to add a link to each tab on my page?
Can anybody please help me out?
Thanks already.

Did you try creating a new UI element using any of the wizards provided by GPE or the full version of GWT Designer?
