I guess the package should rather be in Libraries -> Graphics

lowercase: qwt.

I am not sure whether we should use a "depends on" or a "select"
dependency here. Normally, for dependencies on libraries, we use a
"select" dependency, but it's true that Qt is such a major choice in
the system that we may not want to have Qt automatically selected in
the back of the user.

All patches need to have a proper description + Signed-off-by line.

This package makefile doesn't use the proper infrastructure, so it is
unsuitable for merging in the current version of Buildroot. Could you
rework it to use the GENTARGETS infrastructure, as documented at
http://buildroot.org/downloads/buildroot.html#generic-tutorial ?

Thanks!
