It just works like any other DX9 full-screen game, and has its own UI toolkit. To integrate a simple static report, generated from HTML, into our UI, we need to render the HTML to a texture so we can use that to show the report. Nothing interactive required, and no networking required. I'm a newcomer to WebKit so any pointers are greatly appreciated.]
Both WebKit and WebKit2 are very reliant on having an actual HWND. The HWND is used to determine the size of the viewport, whether the page is focused, etc. I don't think there's an easy way to render content without an HWND currently. However, you can hide the HWND (either by moving it offscreen or never making it visible) and capture its contents using WM_PRINT.
