Simple way to link existing WordPress blog to my existing website

I recently returned to my wordpress blog and want to link it to my existing website hosted by GoDaddy. Is there a simple way to link my blog to my website without paying a lot of money (would be great to no pay anything since I am in the process of a re-launch of my business with a limited budget!)? I have done basic website edits first using Dreamweaver and more recently using a Windows application and then uploading it with Filezilla but am not tech savvy. Any advice is appreciated!
