Try this program:
Serif WebPlus 9 - Web Design Software. Serif make their programs very easy to use, and always with beginners in mind and at the same time give you the chance to learn some of the harder stuff.
You can download an earlier version for free, it's version 6.0 but I've got version 7.0 which is more than good enough to make your blog look great:
Free Web Site Publishing Software Download - WebPlus.
It's got a lot of 'point and shoot' about it.
But you can put in some of your own code when you need to.
