I think even in earlier versions there was this "button".

Go to http://download.qgis.org/downloads.rhtml and add the respective
info to your /etc/apt/sources.list

But, why don't you give it a shot with latest QGIS. I think using the
instructions from http://wiki.qgis.org/qgiswiki/Building_with_CMake is
fairly easy to build from source.

So you import an ascii file in QGIS. But if you create a GRASS vector
your attribute data is automatically linked in GRASS data base (I think
for all drivers... dbf, sqlite... whatever you work with)
