wysiwyg user help authoring tool to work with qthelp?

Question

We need to compile to QtHelp (.qch and .qhc). I'm wondering what tool/toolchain would be easiest for this? We'd like a WYSIWYG help authoring tool as our starting point, then run the output from that through whatever we have to to get QtHelp.

We have used Help & Manual in the past, and that's the kind of WYSIWYG interface we're looking for in a help authoring tool. But we need the toolchain to produce simple html pages (one per help topic) that we can use with qhelpgenerator or qcollectiongenerator, as well as create the .qhp's (at least the table of contents and the keywords sections) and .qhcp to generate the .qch's and .qhc. I'm not seeing how Help & Manual can fit into this.

We've looked briefly at Sphynx, but it seems it has extremely limited options for text formatting. For example, it doesn't look like there's any way to change the font, font size, font color, etc. for a section of text. It appears to be actually impossible to have text that is both bold and italic. Looks great for developer documentation, but seems to be missing basic stuff for authoring a user help file. Please correct me if I somehow missed the basic text formatting features!

So, what WYSIWYG help authoring tool do you recommend, and what is the path from that tool to .qch's and a .qhc?
