An interactive IDL widget application intended to provide a flexible tool that allows the user to generate spatially resolved gyrosynchrotron spectra is presented. The object-based architecture of this application provides full 3D interaction with a user-specified magnetic loop geometry. Alternatively, the user may define and pass to the same interface arbitrary analytical or numerical models, including those derived from magnetic field extrapolation, provided that they inherit the generic properties of the base class defined in this package. The default code generating the GS emission from the input geometrical model was developed in FORTRAN based on the Petrosian-Klein approximation, and compiled as a DLL callable by IDL. However, the interactive interface allows interchanging this default library with any user-defined callable code. To illustrate the concept, a simple dipole magnetic loop object is analytically defined, and GS radio maps at 100 frequencies in the 1-100 GHz frequency range are produced. Similar maps produced by this tool were used as input test data in a forward-fitting algorithm that makes the subject of another presentation at this meeting (Fleishman et al. 09-D-83-SPD40).
