Application inside an application and using URL parameter to pass variable values

hello

My requirement is to create a design studio dashboard that will have 2 applications and I should be able to pass variable values from application 1 to application 2. All this should happen in 1 dashboard application.  I have tried using open document functionality

Application1.openNewWindow(URL link to application 2) . It doesn't meet my requirement as I am required to login to the other application in a new window.

Is it possible to add 2 applications in one dashboard.

thanks,

Bhat
