First thought is to use microcontroller to drive LCD. uC can then be connected to PC via USB, for that You need uC that has USART feature. Also, for USART <--> USB comms You need to get TTL to USB converter (try eBay).

Do you want a graphic LCD or a text mode LCD?

For text mode, look at the 16x2 or 20x2 character LCDs based on HD44780 controller. They should run about $10. Then you need a USB microcontroller to control it somehow -- an Arduino Uno for $30 could do it, or a Leonardo clone: http://imall.iteadstudio.com/itaeduino-leonardo.html
If you want color, look at a small LCD shield like this one: http://www.robotshop.com/productinfo.aspx?pc=RB-Ada-75&lang=en-US or this one: http://imall.iteadstudio.com/im120419008.html with a shield adapter: http://imall.iteadstudio.com/im120417008.html

Then you have to actually program it to display whatever you want! And perhaps program the computer to send information to the display.

Another alternative is to buy a separate Microsoft SideShow compatible USB display, assuming you can still find one... ( http://www.engadget.com/2008/09/12/usb-enabled-picolcd-sideshow-display-may-soon-be-a-collectors-i/ )
