Hi. I know a wee bit of C and am dual booting with win98/redhat7.1. Being slightly familiar with C and then checking out GTK website on tutorials for GTK programming i was wondering a few things. First questions was, is GTK the only GUI type programming for Linux? If not, what other GUI type Libraries are there? Also is it possible to make widgets and windows using just the C language?

thanks.
New to Linux and programming

i am not familiar with gui programming. but i know that there are many other GUI libs. Qt is good gui programming tool

C is an adequate language for widgets and windows. but you'll need libraries like GTK etc unless you're planning to write the library yourself.

i'd recommend having a look through the GTK+ / Gnome Application Developement book online at http://developer.gnome.org/doc/GGAD/ takes you through all the gtk+ basics and the more complex gtk based gnome specific widgets in gnomeui. I really like gtk+, works very logically and it's easy to use under c. i have a small number of reservations when it comes to using it in C++, but it's still pretty impressive, and gtk2 is just out now with an improved api and widget set. you might also want to look into glade for a really easy gui builder for gtk/gnome which can output code in c, c++, perl and a bunch of otehr langauges.

GTK (and the same with QT) is easy to use and powerful. And it has great documentation. When you're writing a program using GTK you can use Glade to "produce" your gui easily.
