Haskell is a functional programming language. To create a program, the user applies and composes functions, in comparison to imperative languages, which use procedural statements.

The Haskell Phrasebook

https://typeclasses.com/phrasebook
The Haskell Phrasebook is a free quick-start Haskell guide comprised of a sequence of small annotated programs. It provides a cursory overview of selected Haskell features, jumping-off points for further reading, and recommendations to help get you writing programs as soon as possible.

Applications and libraries/GUI libraries

https://wiki.haskell.org/Applications_and_libraries/GUI_libraries
There is a large number of GUI libraries for Haskell. Unfortunately there is no standard one and all are more or less incomplete. In general, low-level veneers are going well, but they are low level. High-level abstractions are pretty experimental. There is a need for a supported medium-level GUI library.
