Hi Alexandre, QGIS by itself does not offer this functionality. Maybe a plugin.
However, you can use QGIS together with GRASS. GRASS offers this functionality. You'd have to import your text file into a GRASS dataset and then use the command r.contour. See http://grass.itc.it/gdp/html_grass63/r.contour.html QGIS offerst a GRASS toolbox plugin where you can do issue the GRASS commands from within QGIS. I'd recommend reading the GRASS docus or buying the GRASS book by Markus Neteler/Helena Mitasova. Hope this helps as a starter to find more information on the topic.
