GUSEK provide an open source LP/MILP IDE for Win32, packing a custom version of the SciTE editor linked to the GLPK standalone solver.
Please note that the GUSEK is in beta version. It may be unstable, use at your own risk. Advices and questions can be reported to the author.

The GUSEK Project content is hosted at sourceforge.net/projects/gusek. The source can be reached by SVN: https://gusek.svn.sourceforge.net/svnroot/gusek/trunk.
To install GUSEK:
Notes: GUSEK can be added to Windows Explorer contextual menu and associated to GMPL model extensions. See Tools > Windows Integration for options. Warnings: some Windows editions may require GUSEK running with Administrator rights to do the integration. If you move the GUSEK folder you need select this options again to register the new path.
GUSEK can open multiple files simultaneously, using file extensions to identify them:
Specific resources for GLPK models development are in the Tools menu. All others resources are from standard SciTE editor. The most useful commands can be called from keyword shortcuts, toolbar buttons and tab contextual menus. They are:
The models are developed using the default GLPK model language, the GMPL (GNU MathProg Language). Some examples from the original GLPK package are in the GUSEK "examples" folder. The model can be developed in two ways:
Model and data are in a single file with .mod extension. Good for didatic models or single data sets problems.
Before run see if Tools > Use External .dat is unchecked (default).
Model is in a .mod file, but data are in a distinct .dat file. Useful for complex models and dinamic data set problems.
To run it you need check the Tools > Use External .dat menu item. In this way the model and data file need to have the same name with their respective extensions (like prob1.mod and prob1.dat). You can compile, build or go from an opened model or data file.
To make easy handling multiple data files with different names you can use the "default data file" resource. It set one data file to all runs, until you unset it or define another default data file. In this way you can compile, build or go only from an opened model file. To use it:
- To go back to "same name" model and data file you need to uncheck and check the menu item Tools > Use External .dat;
- You can set multiple extra data files: activate each data file to be used and select Tools > Add as Extra .dat File. You cannot repeat data in data files. To disable extra dat files use Tools > Clear Extra .dat Files;
- To help, if you are testing parameters or using multiple data files: you can toggle the status bar (clicking on it) to "edit status" mode or "GLPK parameters" mode.
- To advanced users: the "default data" and "extra data" filenames parameters can be edited in View > Parameters, fields 2 and 3, respectively.
Gusek also support develop of MPS and Cplex LP Models. You can edit, check, run and convert between these formats using the Tools menu items.
Default MPS format is "Fixed MPS". You can check Tools > Work with Free MPS to to run your "Free MPS" models. This item also defines the type of MPS files builded from GMPL and Cplex LP.
