I'm writing a CRM software package, what should I use?

[ScAndal]

Ok guys and gals,
I'm thinking of writing a Customer Management Software package, and I want everything to look like its web based. Much like that of Siebel if you have seen it. I'm wondering what type of software do they use to create that kind of app. I want it browser like, but don't want it to run on a webserver.

Any help would be appreciated.

Thanks,
ScAndal

You want your program to "look" like a browser, but not actually be one? You could do that with any language. All it takes is drawing the user interface so it looks like a web browser. Seems like a waste to me though, it would be a more robust software solution to make it web based since you are already trying to mimik that functionality, and you wouldn't have to do it from scratch.
