There are a lot of articles, especially on Code Project, that can help you get started here.  This is more of a tutorial question and the web has a lot of great developer sites that have these already up and have step-by-step instructions.  If you don't find anything then let me know.

We are developing our own UI type editor. The values set in the type editor are written on the resource files (.resx).

Similar to your approach for StrataFrame.
