How to create gadget on win7?

Question

Windows

There is an idea to write one service, and the essence of the gadget is simply to load html content from the link and that's
it. Are there any tools or services for this?

Answer 1

You can take any gadget from the catalog and rewrite it as you need. They are all in html, xml, js.
As a basis, I propose, in your case, to take "RSSFeeds.Gadget" in the Windows Sidebar program directory;
