if you want something that doesnt require DX loaded to work, you need to buy DX PRO and make a gadget. As for the clock, look in the forums there are DOZENS of analog clocks, and digital ones too.
As for the web page, simply make one of your objects a "URL" object and put in the web address to goto when you click it.
Again, look at some of the widgets on this site you can import them into DX and see how they were made.
God luck.
