How to automatically login to Zoho Docs

I would like to know how to automatically sign in to Zoho and have my Zoho Docs appear.
Is there a scripting tool in Zoho(like a gadget) that will let me enter the userid and password and start zoho docs.

Also can this work on windows and mac platform?
Also can this work on any browser?

Any and all help is welcome.

Thanks.
