Topic: Calculating Font Descriptor Metrics from TTF Font

I have created a piece of software that writes a PDF file and up to this point I have always used the 14 default fonts and therefore never needed to calculate the metrics for the widths and and for the Font Descriptor. I now need to embed a TTF Font in the PDF and have read that you can embed the TTF Font in the PDF by creating a Stream of the Font Program. However, the widths and font descriptor metrics are required when doing this and I would like to know if anybody knows of a resource for how to calculate those values from the TTF Font itself. I have looked into it quit a bit and am sure that my problems lie within conversion from Glyph space to what believe is a PostScript style space in PDF.
The existing program doesn't use the acrobat sdk and is written in C++. The code needs to be as platform independent as possible and therefore I am basically writing TTF support for the application from scratch. Any guidance or direction would be most appreciated.
