I'm working on a popup html window that acts similiar to
wxPopupWindow. (This will allow unicode text and all the html
attributes to be in a popup). It is basically just a borderless frame
with an htmlWindow with no scrollbars. It is working pretty well
except I can't find a way to measure the window height with the text
inserted with SetPage(). The width is fixed (450)
I've tried GetBestSize on both the frame and htmlwindow but it only
returns the minimum size (20, 20). GetTextExtent returns the text
length as a single line i.e. (1000, 13). Is there a way to get the
height a window needs to be for a set width so the popup size can be
set?

well, I know a way to do it, but it seems kludgy. You can render to a bitmap with a wx.html.HtmlDCRenderer(), then call its GetTotalHeight() method to get the height, then draw it to your popup window.
There must be a way to get at the wx.htmlwindows renderer and call it's GetTotalHeight method, but I can't see it with a quick look through the docs.
Maybe this is enough of a hint to help you find it, though.
Enclosed is a little example of using wx.html.HtmlDCRenderer() to render html into an off-screen bitmap.
