1. A Hifi component with HDD.
2. The component should be controlled with a touch screen input device (12 cm X 8 cm would be great).
3. Touch screen should be detachable
4. Should look like a Winamp or Windows media player

5. Should be availble for less than 10,000
Cha_Indian, what you are looking for is a music server. There are some made by companies such as Linn, CA, NAD etc. None of these are cheap. In addition, these units have version and file compatibility issues. As new formats emerge, you need to find ways to upgrade these players.
A better option (and much cheaper if you already have a PC) is to store all your files on the PC, use whatever programs you want to manage them, and find a way of streaming your files to your audio system. In streaming, I think the best for the last few years has been the Squeezebox. Nothing comes near it at that price point. I think you can pick up a Squeezebox in India for about 15,000. Of course there are others such as Sonos, but they are more expensive.
Using a PC also makes more sense. Hard drives have become ridiculously cheap. I believe a 1TB drive is available today for less that 7,500. Most media servers are restricted by HDD size, as the vendors flaunt their superior musicality, ease of use, and other features. I am sure a good sound card can give you better output than most of these servers.
If you are a little averse to streaming, find a portable player and use that for some time till you refresh the songs in it. In my mind an iPOD and Wadia's iTransport is the most elegant solution. But of course, if you don't like the iPOD, that is out. The problem with other portable players (some of them are really nice and play FLAC files also) is the connectivity and other issues, particularly from third party vendors.
Cheers
