72782 Whois Look Up

I need a simple Whois script like this : [login to view URL] Extensions required : .com .net .org .info .biz I'd like it to have drop down menu instead of radio buttons like the one on the link i specified . It doesn't need to have a order button or something like that I just would like it to have a simple output that opens in new window (try the demo script I provided , whois a domain and it shows Details link and when you click on it). I don't want it to be looking beautiful but I need something nice . (may look like the one i provided.)
