Custom Content type Programmatically

Question

HI,
I am using sharepoint server 2007 in windows server 2003.
i am successfully created custom content type using MS office templates(using SharePoint GUI). now i want to do below things programmatically (want to know whether it works or not).
1. creating custom content type and assigning a template to it programmatically.
2. using these content types in document library (i have written code and working perfectly).
for the 1st point This Link tells that we can't create content types in SharePoint 2007 but we can in SharePoint 2010,
my question is are their any alternatives????? or links will be sufficient.
for 2nd point , i have created custom content types using SharePoint GUI and
adding them to document library programmatically which works perfectly no prob. in this.
Please suggest me if their is any way to create custom content type programmatically.
Regards,
Jithendra.
