Hi
I have attached the layout of a layout application. Can u please tell me if
this kind of application is possible in Cocoa?

In case if u people are not able to open the attachment, I'll explain it.

there is a top frame, containing the banner. and the left side frame
contains the buttons - links to different frames that should be loaded on
click.
eg: "register" window/frame should be loaded on the right target frame, on
the click of the "register" button in the left frame.
and similarly with the "Login" window/frame should be loaded on the right
target frame, on the click of the "login" button.

If this kind is possible, can u please tell me how to go about it in Cocoa..
I'm a newbie in this field.(basically a java programmer) any help will be
highly appreciated.

Regards
Aths
