PDFSharp - Can we use it?

We've lined up the controls that we want to use for the host app. It looks like we can use GTK# TreeView controls for a lot of the utility views (project list, files list, activity log, etc.). The biggest challenge we have is we need someway to design forms and reports. For v1. we're just hoping to get something to translate XML to a dynamic control UI. I'm also checking out PDFSharp for export to PDF. OOXML or ODF will be our format for Word/Excel (if we can figure it out).

Update:

I think MigraDoc / PDASharp may be a real possibility (the same folks who created PDFSharp created MigraDoc). Also taking a look at ITextSharp.dll.
