Hello Jane,
May I know what do you want to exactly do on the remote SQL server ? If you need only create databases and edit them, there are many remote administration tools for SQL server. Here is one from Microsoft itself.
However the speed will not be top. This will depend on where this tool is hosted. (The tool is actually an asp.net web application)

This requires you to setup one .net server. .net framework is free and is available in many magazine CDs.
