grayspaceguru blog space

I have an existing website (www.grayspaceguru.com) that was developed in Word Press. I want to add an easy (for me) blog. I'm not interested in learning Word Press or re-developing my website. I want an application that I can develop in something like Microsoft Word (capable of graphics) that I can develop the blog in and with the click of a button upload to my website.

My primary customers are large and small power generation facilities. I'd like the blog name to be tphobbitenergy.
