Gent was born on a farm to Pieter Gent and Martha Veldsteen near Berganz (he claimed he was descended from Wilhelmus Veldsteen). Wilhelm joined the Liberal Party in 1956 and participated in the 1957 General Elections as a candidate for a seat in the House of Representatives. Winning that year, he would be re-elected until 1985, becoming the longest-serving Brunanter senator (28 years). Gent ran for the Senate in 1985, where he handily defeated his opponent. In 1989 he won, but with a lesser margin and in 1993 he failed to get elected. He took a back seat in politics and moved to Donderstad. In 2003 he made the intent that he would return to politics. In the 2005 General Elections he was elected to the House as a FLP member, and re-elected in 2007. In 2009 he was elected to the Senate as a Mariaberg Parish representative, but announced in November 2011 that he left the FLP and was now a member of the Brunanter People's Party.
