Building GUI projects with D

[karis njiru]

Hi. Am a computer science student from Kenya and decided to use D 
for my class project on Principles of Programming Languages. Am 
having a lot of fun with D but have come across an issue. I have 
been using Visual D for the past 2 months for my coding but after 
a lot of research i found out that i cannot build GUI projects 
with visual D. So i took on Entice Designer which for the past 
week has been a nightmare for me to compile my code error being 
the system cannot find the path in the command prompt specified. 
I have installed DMD and DFL lots of times but there is still the 
same issue. Please help
