We have a BlitzPlus module in development which is being used to develop the Windows BlitzMax IDE (written in BlitzMax), I can't say whether it will be available on release or if it will be free etc.
There is also a linux compatible version (wrapper features same BlitzPlus command API) using the fltk library which will hopefully make many BlitzPlus apps cross platform, again the BlitzMax beta IDE for Linux uses this module so it is also nearing a releasable version also.
