GTK+ stands for GIMP Tool Kit and it is a package of libraries to develop programming languages in Linux, The name GIMP comes from the first application programme by this tool.
In this case, we encounter a routine emulator that allows to develop programs in a flexible way. GTK+ is designed to use other programming languages, such as Phynton, PHP, Pearl, C, C++, C#, and Java, that is why the products processed with this application have a huge potential.
The greatest advantage of GTK+ is that it is a software prepared to create Graphical User Interfaces with a lot of versatility. With this program, the work on graphical environments such as XFCE, ROX y GNOME results much simpler, that is why it will be very useful to those who program over Linux.
