That will be very difficult to manage by uploading through Moodle Sanjay. I use a lot of FrontPage webpages in my Moodle courses, but my website has FrontPage server extensions installed, so I can build and maintain them directly on the website and just link to them from Moodle.
As you know, when you build frames pages, you are dealing with multiple pages and they are linked together by FrontPage...you can upload the individual pages, but Moodle (or your webserver) will have no way of knowing how to display the frames. Also, any pages with images will have problems since you will need to upload the images separatley.
Building webpages in FrontPage (or any other web authoring software) is great, in my opinion, because it keeps the pages in the file system instead of creating them in the database. But, to get maximum use of this, you really need to build them on the server or at least build them and ftp them to your server and link to them from Moodle....just my opinion.
