QSource-Highlight is a Qt4 front-end for GNU Source-Highlight. You can highlight your code on the fly, and have the highlighted output in all the formats supported by source-highlight (e.g. HTML, LaTeX, Texinfo, etc.). You can then copy the formatted output, and paste it (e.g. in your blog) or save it to a file. A preview of the highlighted output is available for some output formats (e.g. HTML, XHTML, etc.).
