pgfgantt - Two labels for one bar in Gantt chart

Question

In my Gantt chart (I'm using package pgfgantt), I have just one task in each line, one bar per task. Each bar has its corresponding label identifying the task aligned left of the chart; e.g.,

\documentclass[10pt,a4paper]{report}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage{pgfgantt}

\begin{document}
\begin{ganttchart}[y unit title=0.4cm,
                    y unit chart=0.5cm,
                    vgrid={draw=none, dotted},
                    hgrid, 
                    title label anchor/.style={below=-1.6ex},
                    title left shift=.05,
                    title right shift=-.05,
                    title height=1,
                    bar/.style={fill=gray!50},
                    incomplete/.style={fill=white},
                    progress label text={},
                    bar height=0.7,
                    group right shift=0,
                    group top shift=.6,
                    group height=.3,
                    group peaks={}{}{.2}]{12}

    \gantttitle{2012}{12} \\
    \gantttitle{October}{4}
    \gantttitle{November}{4} 
    \gantttitle{December}{4}  

    \ganttgroup{Group 1}{1}{8}\\
    \ganttbar{Task 1}{1}{2} \\ 
    \ganttbar{Task 2}{3}{4} \\ 
    \ganttbar{Task 3}{5}{6}\\ 
    \ganttbar{Task 4}{1}{8} \\ 
\end{ganttchart}
\end{document}

Now, I would like to be able to add the resources assigned to each task by inserting an inline label right of each bar. I have had a look at /pgfgantt/bar label, which offers a number of configurations for adjusting labels associated with a bar, but I cannot find a way to use it for having two labels (offline and inline) in one label. Is there any way to do this using pgfgantt?

This picture shows the compiled code from above plus red labels indicating what is it that I want to achieve.

Welcome to the site, freieschaf. Please could you provide a compilable LaTeX document (starting with \documentclass and so on) that shows what you have got so far, and perhaps an annotated picture to clarify exactly what you want to achieve? — John Wickerson, May 08 '13 at 14:28
Thanks @JohnWickerson! I edited my question with your suggestions, hope it is easier to understand now. I did not attach the picture directly because I need higher reputation to do so. — freieschaf, May 08 '13 at 14:46
There is progress label and various keys/styles to change its appearance. — Qrrbrbirlbel, May 08 '13 at 14:59
I see now that you actually have emptied progress label text={} in the optional argument to the ganttchart environment … — Qrrbrbirlbel, May 08 '13 at 15:22

Yes, that looks quite good, I will look at it carefully in a while. But actually, resources and their percentages don't have anything to do with the progress of a task: a resource works on the task, and its dedication (the percentage I added) means how much of their work effort goes into that task. I don't want to use progress on my chart so that's why it was empty in the gantchart options. Other than that, this could be a decent solution if I set progress=100 in every bar. — freieschaf, May 08 '13 at 17:30
Well, yes, then just use progress label text=Resource 1 (50\,\%) for every bar. I have updated my answer. This way you do only have to specify Resource and (optional) the percentage. — Qrrbrbirlbel, May 08 '13 at 17:48
