Data mining / Auto Classification /Rules extraction - repost

Hi! I have a dataset with 10000 cases and 10 variables + 1 class variable I need a software that using back propagation classify the data and generate rules to predict to which class a new case should be associated to. Please describe your experience in data mining and how do you plan to solve this job. Here's a sample of the dataset: PP -0.061 0.08 -0.0261 0.024633333 0.025816667 -0.015491667 0.000663889 0.007277778 0.002922222 0.006485764 PP 0 0 0.0498 -0.019733333 0.013483333 -0.0208 -0.011105556 -0.000694444 0.003819444 0.007812153 PP 0 0 -0.0939 -0.019866667 0.013483333 -0.012558333 -0.010069444 -0.000694444 0.002625694 0.007813889 GP -0.789 0.500333333 -0.0459 -0.0833 -0.02665 -0.145816667 -0.069997222 -0.035118056 -0.0114375 0.003848264 GP -0.79 0.266333333 0.05 -0.029 -0.06665 -0.154158333 -0.073830556 -0.035116667 -0.014156944 0.003750347 GP 1.35 -0.626 -0.3 -0.133133333 -0.08315 -0.144675 -0.075 -0.040693056 -0.015625 0.004722222 GP -0.199 -0.044666667 -0.2385 -0.096733333 0.058 0.043316667 -0.039966667 -0.022347222 -0.00680625 0.002223264 GP 1.971 0.657 0.197 -0.014366667 -0.083883333 0.08305 -0.027844444 -0.024297222 -0.007731944 -0.000972222
