Is it possible to create a buffer around neighbouring polygons, so that the new polygons do not overlap?
Preferably in QGIS but any other tool will do.
So instead of the first result I would like to obtain something similar to the second:
[GIS] Buffer neighbouring polygons without overlap using QGIS

If you leave the "Dissolve buffer results" unticked it should work fine
You can use the "Intersect" tool on the buffer and land use layers. This should create a third layer where buffers are "cut out of" the land use polygons. Then you can calculate the area of the resulting polygons using Field Calculator.

and after the Intersect operation and calculation of area using Field Calculator:
Divide by the total area of the buffer to obtain percentage values.

One way to do this, depending on the quality/complexity of the polygon layer, is with the following steps:
1) Extract vertices from polygons, ensuring a unique field is kept as an attribute
2) Create a voronoi from these points
3) Buffer the original polygons by the required amount
4) Subtract the buffer polygons from the voronoi
5) Recombine/dissolve the remaining voronoi polygons on the unique attribute field
When doing this in the past with slightly inconsistent datasets I've had to do additional steps to remove artefacts from within the new polygons:
The advantage of the voronoi step (as also suggested by csd) is that it gives perpendicular boundaries, as your requirement diagram showed.
Some of these operations can take significant amounts of time though....
