Hi Alex, welcome to the Flink community! Right now, there is no way to specify a Flink program without writing code (Java, Scala, Python(beta)).
In principle it is possible to put such functionality on top of the DataStream or DataSet APIs. This has been done before for other programming APIs (Flink's own libraries Table API, Gelly, FlinkML, and externals Apache Beam / Google DataFlow, Mahout, Cascading, ...). However, all of these are again programming APIs, some specialized for certain use-cases. Specifying Flink programs by config files (or graphically) would require a data model, a DataStream/DataSet program generator and probably a code generation component.
