I've got a txt/csv file with the utm coordinates and the hights. Now I want to upload this into qgis. This is not a problem so far. The problem is to create a shapefile out of the data with an attribute table for adding other values to work with. Has anyone an idea how to do this?

I think you were missing closing your output text file - until you do that, you won't get anything written to the text file. Below code tested and works:
import arcpy
arcpy.env.workspace = r"C:\Users\chad\Documents\ArcGIS\Default.gdb"
arcpy.BuildRasterAttributeTable_management("raster17", "Overwrite")
outfile = open(r"D:\temp\raster17.txt", "w")
rows = arcpy.SearchCursor("raster17","","","Value;Count","")
for row in rows:
val = row.getValue("Value")
count = row.getValue("Count")
print val, count
outfile.write(str(val) + "," + str(count) + "\n")
outfile.close()
And it yields this text file:
You can use the Geometry Export to CSV function on your shapefile to obtain coordinates via:
MMQGIS > Import/Export > Geometry Export to CSV
Make sure it is enabled in Plugins > Manage and Install Plugins...

There's a plugin called Add Delimited Text Layer. I believe it is included in a default 1.8 install. Once the plugin is enabled, an option appears in the Layer toolbar and menu, where the Add Vector, Add Raster, etc. options are. The wizard should be self-explanatory, but feel free to ask further if you experience issues.
An imported text file still can't be edited by QGIS. Once you've imported the layer, you can use Layer > Save As... to save a shapefile, or any other format. Save the shapefile and then import it into QGIS, and you can edit as normal.
