Well, ASP is a Microsoft language. Not sure how you feel about Microsoft but they do have Express versions of their Visual Studio Integrated Development Environments which should give you enough tools to do what it sounds like you want to do. I use Visual Studio for work but the full-fledged versions. Moving those files from ASP to something like ASPX (ASP.NET) is a good idea since ASP is considered an older language and Microsoft is going to end support on it in 2009 or 2010. My suggestion for you is to check out Visual Web Developer 2008 Express Edition. It may be all you need especially if you worked with FrontPage before.
