Frontpage is realy bad software.If vote for microsoft frontpage or macromedia dreamweaver, i choose dreamweaver... is realy professional tool...I use macromedia home site. It realy cool for creating sites with many pages.
You can't Use Win32api Via Php for creating internet sites... I think it can be used onley with Active-x dll or Active-x controls in your visual studio, but not for web pages...
