Here are some html pages that might encourage interest in Freepascal, and XForms toolkit. http://www.sytekcom.com/eng/FreepascalXFormsToolkit.html and http://www.sytekcom.com/eng/FreepascalXFormsColorbrowserDemo.html There are 4 files in the first link. If you select all, then paste into a text editor, you can separate the files at the hash marks and save as the filename given. Freepascal should compile the last 2 (cursorfont and Data_Unit) together, first. Then Types_Unit file. Then the first fp_XForms_Unit.pp file. Of course you will need freepascal and forms library installed first. The fp_XForms_Colorbrowser.pp file will compile most easily in the same directory. Just type "fpc filename". The resulting executable works better than the library original that has a small bug. What is nice is how structured pascal is. Not case sensitive. Records and Objects can be built from C functions. Even linux system calls. XForms callbacks are more properly handled in this freepascal toolkit. I don't urge anybody to keep my naming conventions. But some might recognize Arduino is more pascal than C. A rather oustanding documented compiler, and same for XWindow toolkit, free for trying on linux.
