Creating UI's in Designer7.0

Hi Folks,

I have designer7.0 and i want to develope some UI’s. But it seems 7.0 wont support developing UI’s(perspective not available). I see 7.1.2 documenetaion and it seems we can develope UI’s.
Could you guide if we have any alternative or if i am totally wrong.
I can go for a basic java script/HTML for that. But wanted to try with designer.

Thanks in Advance
